1. GENERAL INFORMATION

1.1 Introduction In the Netherlands, graduate schools have been founded for a variety of scientific disciplines. Interuniversity graduate schools are schools in which several Dutch universities participate, as laid down in a formal agreement between the Executive Boards of the participating universities. One of the universities is responsible for the daily organization and administration of the graduate school, including the organization of the PhD educational programme and various scientific activities. These activities are conducted under the responsibility of a scientific director, often, but not necessarily, one of the professors of the university that is in charge of the administration. The primary aims of graduate schools are to provide additional education and training for PhD students of the participating institutions and to foster scientific contacts and collaboration. For the Graduate School on Engineering Mechanics, the aims have been particularized in the Mission Statement, presented in section 1.2. Until 2014, Graduate schools could be accredited by the Royal Netherlands Academy of Arts and Sciences (KNAW), which gives a mark of quality. The accreditation was given on the basis of a proposal in which a coherent educational program for PhD students was described as well as coherence in terms of research between the participating teams. Accreditation was given for six-year periods. After such a period an application for renewal of the accreditation could be filed at the KNAW, which consisted of a self-assessment over the past period, together with a peer review based on a site visit, interviews and this self-assessment. The Graduate School on Engineering Mechanics was founded in 1996 and received a five-year accreditation of the KNAW directly at the first application in 1997. It embraces all research groups that are active in the field at the Eindhoven University of Technology, the Delft University of Technology and the University of Twente, with the Eindhoven University of Technology acting as the commissioner, hosting the secretariat. In 2001, 2006 and 2012 a peer review of the activities of the Graduate School over the first, second and third period of operation by an international review panel took place and in 2002, 2007 and 2013 the ECOS/KNAW-accreditation of the Graduate School on Engineering Mechanics was renewed. In 2014, the KNAW decided to completely abandon the accreditation procedures for Graduate Schools. This implies that the present period of 6 years is the last one for EM, in which the accreditation label still applies. The Graduate School on Engineering Mechanics represents the internationally active groups of the Dutch universities of technology in the area of engineering mechanics. The EM-school also co-ordinates and tunes the research activities in the participating groups (e.g. through the 3TU Centre of Excellence), and it has developed a complete graduate course programme in collaboration with the JM Burgers Centre (Graduate School on Fluid Mechanics). It can therefore be considered as the representative scientific platform in the Netherlands in the engineering mechanics field. This platform sets the strategic directions of future research in the Netherlands in the engineering mechanics field, and it is responsible for the quality of future generations of PhDs, who are the primary determinants of the quality of future activities in this area in the Dutch industries and universities. In the Graduate School on Engineering Mechanics, the individual research groups have an essential responsibility in executing their individual research programs. On basis of consensus, the graduate school thereby stimulates certain focal areas of research. More importantly, it exercises

6

a quality control on the level of research, since it has adopted a lower bound for the quality of the participating groups, which derives from the research assessments at the level of the university departments that are commissioned by the Netherlands Association of Universities (VSNU).

1.2 Mission

The Netherlands Graduate School on Engineering Mechanics has been established with the aim to strengthen research and education in the field of engineering mechanics in The Netherlands. The EM Graduate School intends to be a platform that, on the basis of a number of selected research themes, fosters long-term knowledge and skills in the engineering mechanics field. Although operating primarily at a national level, it intends to stimulate international collaborative research projects within the research themes. Within the foregoing global objectives the following more specific objectives can be formulated:

Training of PhD-students to become qualified independent researchers in the field of engineering mechanics according to international standards. To this end, a series of high-quality graduate courses is developed on specific subjects.

Co-ordination and tuning of the engineering mechanics research activities in the participating groups. Furthermore, the Graduate School aims at strengthening the available infrastructure for research in engineering mechanics. It can be stated that the present infrastructure meets high international standards.

Selection of the main research themes in engineering mechanics carried out within the EM Graduate School. These research themes are being characterized by a strong international

position of the research in the Netherlands, while at the same time they are of importance for Dutch industry and society.

Strengthening of the international scientific position and the international visibility of The Netherlands in the engineering mechanics field.

Cooperation with industries and technological institutes to promote the mutual exchange of knowledge on engineering mechanics.

Maintain close connections and cooperate with related fields of engineering.

Stimulate nation-wide thematic discussions, streamlined research strategies and organization of workshops for representatives from industry, technological institutes and project leaders to

discuss the needs of industries with respect to scientific research.

Guarding the standards of undergraduate education in the engineering mechanics area at the Dutch universities. This is done in particular by influencing policies with respect to the

appointment of professors and other senior staff in this area.

Attracting highly qualified engineers, prospective and established scientists to the Netherlands.

1.3 The field of Engineering Mechanics

Engineering mechanics is concerned with the description, analysis and optimization of the static and dynamic behaviour of materials, products and mechanical processes. Solid mechanics is at the heart of engineering mechanics, but is not necessarily identical to it. Traditionally, engineering mechanics is one of the fundamental cores of engineering sciences such as Aerospace Engineering, Civil Engineering, Mechanical Engineering and Maritime Technology.

7

Assisted by a steady growth in computational power, resources and efficiency, new challenges and perspectives for the engineering mechanics field have emerged. Contemporary developments of engineering mechanics include the following major directions:

Prediction of structural mechanical behaviour from material mechanics and establishment of structure-property relations for engineering materials and structures, including the ultimate failure of the material or structure. The ultimate aim is to bridge the gap between science and technology in the area of materials processing and design, via computational modelling and experimental analysis of the full thermo-mechanical history of material during their formation, processing and final design, in order to be able to quantitatively predict product properties. This equally applies to structures composed of these materials.

Prediction of the dynamic behaviour of engineering systems with full account of nonlinearities and multiphysical dynamic interaction and experimental identification under operational conditions. This area is of crucial importance in many practical dynamical systems where friction, contact and other nonlinearities have a substantial effect on the dynamic behaviour.

Optimization of products, processes and systems by means of computer simulations to enhance the reliability and to tailor their mechanical behaviour for the particular application. Here, it is assumed that the simulation of the mechanical behaviour can be carried out in a sufficiently accurate way, while the optimal design is traced numerically. Among typical application areas, the following can be highlighted:

miniaturization & micro-technology: design, optimization, processing and functionality of MEMS (micro-electro-mechanical systems) and NEMS (nano-electro-mechanical systems); processing, performance and reliability in SiP (systems in package); low-k solutions in IC-technology; lead-free soldering; 3D printing…

high-tech consumer applications: flexible displays; flexible photovoltaic cells; lab-on-a-chip systems; RF-MEMS wireless technology; …

high-tech materials: metastable materials; shape memory alloys; TRIP-steels; GLARE; Ni-based superalloys; thermoshock materials; high-temperature engine materials; self-healing materials; thermoplastic composites, …

innovation and optimization in manufacturing: polymer-coated sheet processing in packaging; discrete die forming; damage engineering in metals; paperboard engineering; friction stir welding; …

dynamics of materials and structures: nonlinear control of motion systems and robotics, vehicle dynamics, tire dynamics, acoustics and control, structural acoustics and noise control, structural health monitoring;...

construction engineering: collision-proof ship hulls; damage control in masonry and concrete structures, …

topology optimization of smart structures As a consequence of the above developments, the traditional boundaries between solid and fluid mechanics are sometimes fading. This happens, for example, in fluid-structure interaction (FSI), in the field of mechanics of materials and in the area of acoustic radiation of structures. In addition, the interactions with other areas of engineering sciences, such as materials technology, thermodynamics and systems and control, become of increasing importance. Finally, it is noted that the successful implementation of the abovementioned developments in practical applications relies on prior experimental validation of the developed simulation tools and physical models. This requires an increasing interaction between computational modelling and experimental analysis.

1.6 Research themes

An important goal of the Graduate School on Engineering Mechanics is the co-ordination and combination of research activities of participating groups. In accordance to this it was decided to group the research activities into three research themes: 1. Computational and Experimental Mechanics

This research theme is related to the potential of modern computational and experimental techniques for solving problems in mechanics. Much attention is paid to optimal numerical procedures and to large-scale computing. Important applications are in the field of crash simulation of vehicle systems, simulation of production processes, in particular forming processes, as well as complex structures in civil engineering and aerospace engineering.

2. Structural Dynamics and Control This research theme is related to the dynamic behaviour of engineering structures. Particular attention is paid to nonlinear dynamics and fluid-structure-interaction. Also of importance is the interaction with control. Important applications are in the field of rotating machinery, noise reduction and drive systems.

3. Reliability and Optimization This research theme is related to the development of design procedures based on reliability, as well as to structural optimization with respect to mechanical behaviour. Important applications are in the fields of biomedical technology (e.g. heart valves) and in the field of thin-walled structures.

These research themes fit well with the major directions in contemporary engineering mechanics as described in Section 1.3. Furthermore, they are characterized by a strong international position of the research in the Netherlands, while at the same time they are of importance for Dutch industry and society. Point of departure in all research themes is the development of models based upon the principles of engineering mechanics. These models necessitate and motivate the development of contemporary numerical and experimental tools for solving engineering mechanics problems. The application of these tools in computer-aided design and production processes results in a decrease in the development time of advanced products, and thereby time-to-market, for instance due to a reduction in the required amount of prototypes. Also, an increase in product quality and a reduction in production and operating costs are worth mentioning, improving competitiveness. The optimal use of computational resources for complex numerical simulations

11

as well as the incorporation of nonlinear phenomena in the modeling is common to all three themes.

Research groups participate, depending upon their expertise and affinity, in several themes:

1.7 Education

The most important goal of the Graduate School on Engineering Mechanics is the formation and education of graduate students to become independent researchers in the field of Engineering Mechanics. In accordance with this, the Graduate School offers a national four-year training program for PhD students in the field of Engineering Mechanics. It consists of a programmatic part and a PhD research project, accompanied by a personal plan of education and supervision per PhD student. In addition to these joint courses the programmatic part contains an individual course program, with initial and post-initial courses selected from the programs offered at participating groups. Furthermore, participation in workshops and summer schools under guidance of foreign visiting lecturers forms part of it, as well as practical work at foreign top institutes.

12

1.7.1 Course curriculum The PhD research project covers about 80% of the four-years training program. Research topics are in connection with the research program of the Graduate School. As the research approach within the Graduate School is thematically oriented, research students get the opportunity both to deepen their knowledge in the context of their own project and to broaden their vision on the research field as a whole. The programmatic part of the training program, including personal and professional skills covers about 20% of the four years training program. The heart of it is formed by a joint series of EM graduate courses, in close connection with the selected research themes. PhD-students can take part in the courses, providing the opportunity to keep track with developments in the field of engineering mechanics outside their own focus of research. EM-graduate full courses all follow a general framework, which consists of two three-day clusters of lecturing, alternated with (computer) exercises to obtain hands-on experience. In principle, staff members of the participating universities teach the courses, inviting (international) experts in the field as guest lecturers where relevant. The programme successfully started in 1998. All courses are evaluated systematically and results are discussed with lecturers and Governing Board. In general, participants are very content with the courses, appreciating their relevance and the new knowledge and information offered. Furthermore, courses enable a fast and effective interaction between research and education. To keep the connection with the selected research themes actual and up-to-date the contents of individual courses is regularly updated. The present courses organized by EM are listed below:

- Continuum thermodynamics Topical course

- Optimization and parameter identification Topical course

- Nonlinear material mechanics Full course

- Solutions methods in computational mechanics Topical course

- Solving structural acoustic coupled problems Topical course

- Stability of Structures Full course

- Mechanics in microsystems Topical course

- Discontinuities, interfaces, fluid-structure interaction, multi-phase Topical course

- Mechanics of large deformations Topical course

13

1.7.2 Structure of the Engineering Mechanics PhD course programme for the period 2011-2015

In 2008, a new course programme has been established in the interest of the PhD students and

Post-Docs. Key characteristics are: a two-years cycle course programme, formal registration of

credit points, more courses and courses of different type (broad or in depth).

Details are provided below:

The minimum educational load for PhD students is 15 credit points (one credit point is equivalent

to one ECTS-credit and will be further referred to as EC), i.e. 1/4 of a year. After completing the

programme, a PhD student receives a formal certificate, as proof of his/her successful

participation in the EM course programme.

Boundary conditions:

The courses have to be attended completely. PhD students who only attend a part of a course will not receive credit points for that course.

Each individual has to supply a written proof of the successful completion of a local or external course, to be signed by the supervising professor (promoter).

The EC-equivalent of each course will be determined at 0.5 EC/day.

In order to obtain credit points for an external course that has not been previously approved by EM, the PhD student must request for an approval prior to the start of the course.

In order to obtain the EM certificate, a PhD student must have attended the EM symposium at least 2 times during the PhD contract.

EM will publishes a full course calendar on its website.

PhD students who collected a minimum 15 EC, receive a formal certificate, formally handed over during the annual EM symposium.

Outline of the structure of the EM-courses in the programme:

Duration of a cycle in the course programme = 2 years.

Full courses (3 EC): 6 day courses covering the wide scope of key areas in EM. Two such courses are organized every year, i.e. 4 courses in a cycle of 2 years. These courses include a rapid summary of basics followed by advanced topics that are beyond the MSc level.

Topical courses (0.5 or 1 EC): 1- or 2-day courses on specific subjects, for a smaller group of participants. These courses may either strengthen the generic basis or provide specific in-depth knowledge. About 8 such courses are offered in a 2-year cycle.

Recognized courses and allowable share within the programme:

EM-courses and workshops: PhD courses organized by EM (details below). Minimum share = 8 EC.

Recognized external courses organized by external graduate schools or institutes and approved by the EM board.

Master courses given at local institutes to patch missing skills in the training of a PhD student, as required for his/her particular project. If MSc courses are taken, the course exam is compulsory and has to be passed. Maximum share = 5 EC.

Additional courses such as presentation skills, technical writing, etc. can also be mentioned on the certificate.

14

On request of the PhD student, EM will provide the promotor with a list of the EM-courses he/she

participated in. On the basis of this list and on the request of the PhD student, the promotor can

make a letter stating the full overview of all courses taken in the educational plan of the PhD

student applying for this letter.

EM courses

All EM courses are integral part of a 2-year programme, listed in the sections 1.7.3 (cycle 2015-

2016 and 1.7.4. (Provisional planning cycle 2015-2016)

1.8 General description of developments in 2015

2015 was another successful year for the graduate school EM. Like in the previous years priority was laid on the continuation of the research activities in the field of Engineering Mechanics. This resulted in the following overall output for 2015:

Scientific publications: refereed journals 226(14*)

Scientific publications: books, chapters in book 15

Scientific publications: refereed proceedings 129

PhD theses 25

* Publications in co-operation between different EM-groups

This output is documented in more detail in subsequent chapters of this Annual Report To stimulate the exchange of information on ongoing research within the Graduate School, the Eighteenth Engineering Mechanics Symposium took place on October 25 and 26, 2015 in congress centre “Hotel Papendal” in Arnhem. One hundred fifty six members of the senior academic staff and PhD-students participating within the Graduate School attended the Eighteenth Engineering Mechanics Symposium.

18

Prof. Dr.-Ing. Stefanie Reese presented a keynote lecture, entitled “Computational modeling from the material point to the black box” The topics of the Workshops at the 2015 EM Symposium were “Composites”, “Frictional cohesive materials”, “Thin walled and flexible structures” and “Wave dynamics” . Each of the workshops started with a Plenary Introduction by the Workshop Organizers on the trends and challenges of the topics of the workshops. Next, two of the actual Workshops were scheduled to run in parallel on the first Symposium day, whereas the other two were scheduled to run in parallel on the second Symposium day. Each Workshop consisted of two parts, separated by a break. Each part consisted of two presentations by PhD-students/Postdocs. In conjunction to the oral presentations there was a PhD-students presentation contest, awarding a prize for the best PhD presentation at each of the Symposium Workshops. Members of the jury were the Workshop Organizers. Winners of the PhD-students presentation contest were: Iuri Rocha (TUD) with a contribution entitled “Hydrothermal Ageing of Glass/Epoxy Composites for Wind Turbine Blades”, Stefano Muraro (TUD) with a contribution entitled “Stress-strain behaviour of peats; an experimental insight”, Zhao Mingjuan(TUD) with a contribution entitled “3D wave scattering by a cylindrical lined tunnel embedded in an elastic half space” and Salman Shafqat (TU/e) with a contribution entitled “A novel bulge test based characterization methodology for buckled membranes”. In two poster sessions 78 PhD-students and Postdocs of the EM Graduate School presented their current research project. This resulted in stimulating discussions on running projects. In conjunction to the poster sessions a poster contest was organized in which a jury selected the best three contributions. The jury consisted of the following members: Dr.ir. L.F.P. (Pascal) Etman, Dr.ir. E.S.(Semih) Perdahcioglu, Prof.dr. C.(Chiara) Bisagni, Dr. ir. F.J. (Frans) Klever.

Winners of the poster contest were: M. Malagù (TUD) with the poster “Computational modeling of size effect in carbon nanotubes and carbon nanotube reinforced polymers ”, A. Ruybalid (TU/e) with the poster “Shedding lights on materials in LED’s”, A. Torkabadi (UT) with the poster “Controlling springback of Advanced High-Strength Steels by understanding the elastic and anelastic behavior”. The contributed posters are published in an information brochure. The winning contributions can be found on the EM website http://www.em.tue.nl/history/index.php/6 Additional remarks:

The Annual Report 2014, with information on participating research groups, was published in 2015. It was distributed among participants and relations of the Graduate School.

There was a meeting of the Advisory Board of the Graduate School on Engineering Mechanics on October 28, 2015, which took place after the Eighteenth Engineering Mechanics Symposium. At this meeting the future strategy and directions of the EM Graduate School were discussed.

There was a meeting of the board of project leaders on October 28, 2015, in which the EM activities were evaluated and the Seventeenth Engineering Mechanics Symposium was discussed. Plans for the Nineteenth Engineering Mechanics Symposium, to be held 25-26 October, 2016 in Hotel Papendal in Arnhem, were also discussed with all faculty members

19

present. The planned workshop topics for 2016 are: “Optimisation and additive manufacturing”, “Multi-physics and coupled problems”, “Experimental mechanics”, and “Dynamics at the small scale”.

1.9 Memberships: 1.9.1 Memberships

Regular Membership – Group based

The regular membership of the Graduate School Engineering Mechanics is based on the

admittance of a 3TU research group to become a group member of the School. The membership

of a group is based on three criteria:

Research programme of the group:

The programme should fit in the mission of the EM graduate school and there needs to be a

solid basis for co-operation between the scientific group members and other members in the

graduate school. The group’s research programme must have a critical mass that lies well

within EM’s scope.

Scientific performance and quality:

A new research group can be admitted to EM: (1) on the basis of a proven scientific track

record that underpins the quality of the group leader and faculty members, for a group with

established scientists; (2) on the basis of good expectations for scientific quality and

performance for the group leader and faculty members for a new (young) group. If a new EM

group has previously been assessed by QANU, the requirements outlined in section 1.9.4 for

existing member-groups apply for the new group as well.

Expectation for integration in the graduate school:

The integration of a new group within EM implies an active participation in the execution of

EM’s PhD course programme and a regular participation of PhD students in the courses

offered by EM. Group members are expected to participate in the annual EM symposium to

present their scientific progress in the oral and poster sessions.

Group based members of EM either fall in one of the following categories:

Faculty members

Faculty members are junior (assistant professor) or senior (associate or full professor)

researchers appointed at the research groups by one of the respective universities. They have

a prime responsibility in supervising the PhD students and Post-Docs during their research

projects, and in assisting all PhD students during their PhD educational programme. A high

quality of the supervision is one of the key requirements. Faculty members from an EM

research group can be voluntary member of EM if their research focus fits in the EM research

programme. As a member of the Graduate School EM, faculty members are expected to

actively contribute to the knowledge dissemination (PhD course programme) and knowledge

exchange (EM symposium).

20

Post-Docs

Post-Docs are young researchers with a PhD degree, who actively contribute to research

projects in the participating research groups. They can take benefit of the EM course

programme and they are expected to participate and contribute to the yearly EM symposium.

They can also play an active role in the Graduate school, by assisting in the PhD educational

programme.

PhD students

PhD students are the research members of the Graduate school, aiming to obtain a PhD with

the support of the Graduate School and the educational part thereof. The PhD projects are

proposed by the supervisors and typically fit within the scope of the EM research topics. PhD

students belonging to member groups are admitted to the Graduate School on proposal of

one of the supervising faculty members (also EM member). They are expected to fully attend

the EM course programme for 15 ECTS and they are expected to participate and contribute to

the yearly EM symposium.

The membership of a group involves a yearly financial contribution, and an individual (small)

contribution to the EM-symposium. The group and individual fees will be determined yearly by

the governing board of the Graduate School. For the yearly fee, full access to the educational

programme for all subscribed group members is granted.

MSc student membership

Excellent MSc students from an EM research group (i.e. an EM group membership as defined in

section 1.1 applies) that are following a MSc-PhD Graduate programme or who have been

identified as potential PhD students in the master phase already, can be admitted as a MSc

student member of the EM Graduate School. These students need to be registered in one of the

adhering Master programmes of the EM graduate school. MSc student members can be admitted

to the Graduate School upon nomination of the MSc/PhD supervisors (EM members). Admittance

implies that MSc student members are allowed to participate in the EM PhD educational

programme and the EM symposium.

Associate Membership – Individually based

Individual faculty members who are not part of an EM research group (as defined in section 1.1)

can be admitted to the Graduate School as an associate member. They can also propose a

maximum of 2 PhD students or Post-Docs to become an associate (PhD student or Post-Doc)

member. Note that only 1 faculty member from a group can be an associate member. A larger

participation in EM necessitates a group membership. Associate members of EM can be (1)

researchers from a non-EM research group of 3TU, (2) researchers from Dutch non-3TU research

groups that have an established scientific track record of high quality in engineering mechanics or

(3) established researchers of high quality from a non-Dutch group.

21

The associate membership implies that Associate members can participate in all EM events,

including its educational programme. Associate members (faculty, Post-Doc or PhDs) have to

contribute financially to the activities (including EM courses) in which they participate.

Industrial Membership

Companies and institutes with long-term research activities in the field of the Graduate School

can request an industrial membership of the Graduate School Engineering Mechanics. The

industrial membership grants full and free access to all courses of the EM course programme for

research employees working in the company. Moreover, as an industrial member, researchers

from these companies or institutes can attend the EM symposium, where they can also actively

participate in the poster sessions. For registration at the symposium, the EM-researchers regular

fee has to be paid.

The industrial membership of a company or research institute involves a yearly financial

contribution, and the individual contribution for participation to the EM-symposium. The level of

the company and individual symposium fees are determined yearly by the governing board of the

Graduate School.

1.9.2 Selection, admission criteria and procedures

Group membership

A group membership is granted by the Board of the Graduate School. The group leader sends a

written motivated request to the scientific director. The Board decides on the basis of all criteria

and arguments provided. Once the group is admitted to EM, all group members (faculty, PhDs,

Post-Docs) can subscribe to EM by completing subscription. The subscription forms of PhD

students and Post-Docs must be approved and signed by the direct project supervisors.

MSc student membership

Excellent master students, who wish to become an MSc student member, can fill in a subscription

request. This request needs a separate motivation from the responsible supervisors, accompanied

by a list of course marks obtained in the MSc course programme. The scientific director decides on

the basis of all information provided.

Associate membership

An associate membership is also granted by the Board of the graduate school. A formal request

has to be sent to the scientific director. The Board decides on the basis of the established

contacts with EM members, the embedding, expected integration and contribution to the EM

graduate school.

22

Industrial membership

An industrial membership can be granted by the Board of the Graduate School to companies or

research institutes with a strong interest for the EM research activities. To this purpose, the

company or institute sends a written motivated letter to the scientific director. The Board

decides on the basis of all criteria and arguments provided. Once a company or institute is

admitted to EM, its research employees can freely participate in the course activities of the

Graduate School.

1.9.3 Double memberships

Faculty members

Faculty members can be member of more than 1 graduate school. They are nevertheless

expected to play a substantial and active role in each of the graduate schools in which they

participate. To be admitted to the graduate school, at least 25% of the research activities should

fit in EM’s research programme.

PhD students and Post-Docs

Researchers (PhD students and Post-Docs) can be member of one graduate school only (KNAW

requirement).

1.9.4 Quality monitoring & control

Quality expectations

The Engineering Mechanics graduate school expects all its group members and associate members

to aim for a contribution to a high quality research programme. This includes high quality

publications with a good citation impact, keynote lectures, patents or inventions, editorial roles in

international journals, memberships of international assessment committees, etc. In terms of PhD

supervision, a good progress monitoring procedure is expected. It is the prime responsibility of the

group leader to work towards these goals.

Independent assessment

Every 6 years, the quality of the research programmes is assessed by QANU. All research

programmes are evaluated in terms of quality, quantity, relevance and viability. The outcome of

this assessment constitutes the prime feedback on the quality of the research programmes. The

quality of the PhD supervision is monitored through direct feedback from PhD students, either

individually or through the PhD student board.

Monitoring

As a minimum threshold for scientific quality, the QANU marks for quality, quantity, relevance

and viability, according to the most recent version of the SEP protocol, have to be at least 3, 3, 3,

3, respectively.

23

In case a research group underperforms as apparent from the QANU assessment its membership

will be reconsidered by the EM Board. If the supervision of an individual PhD student lacks

quality, the EM management team will directly contact the responsible supervisors to address

the problem.

1.9.5 Additional provision

All situations for which this regulation does not apply will be handled by the Governing Board of

the Graduate School.

1.12 Overview of co-operation

1.12.1 Internal co-operation

With reference to its mission statement the Graduate School on Engineering Mechanics fosters the co-operation between participating research groups. This has resulted in an increasing number of joint research projects that received substantial input from different EM-groups. Joint projects for 2015 are summarized in Appendix A. Furthermore, co-operation between members from different participating groups resulted in a total of 14 joint publications in refereed journals and proceedings.

1.12.2 External co-operation

Within the field of mechanics of materials, the Graduate School on Engineering Mechanics has a long tradition of co-operation with one of the former four leading technological institutes, namely the Materials Innovation Institute (M2i). In recent years, M2i had to change its operational roads in financing research, whereby the present route makes use of the STW-HTM calls, in which M2i represents the industrial partners. The EM projects in this institute form a coherent program that concentrates on forming processes and on the fundamental understanding and the predictive analysis of a number of carefully selected generic industrial problems. The main challenge within this program is the accurate prediction of mechanical properties of materials with complex microstructures, in view of their application in micro-systems (functional materials) and various engineering manufacturing processes. Establishing micro-macro structure-property relations with a particular emphasis on the improvement of materials, processes and products at various scales, is thereby a key issue tackled both experimentally and numerically. The scientific work in this area directly supports the long-term strategy of the industrial partners involved, by acquiring fundamental insight that leads to improved materials and processes. At the same time, the investigated applications in several projects are fine-tuned to a particular industrial request, which provides direct answers to specific engineering questions in industry. The EM Graduate School participates in M2i with 2 clusters

26

(cluster 1 on ‘Virtual shaping and structural performance’ and cluster 2 on ‘Multi-scale fundamentals of materials’). The Graduate School on Engineering Mechanics also co-operates with other universities, research institutes and various industrial partners. External Co-operation: Education With respect to education the EM Graduate School co-operates with other Graduate Schools. It has been agreed that the PhD Students of the EM and JMBC (fluid mechanics) Graduate Schools will be enabled to follow each other’s courses. The same holds for PhD students of the EM Graduate School and the Belgian National Graduate School in Mechanics (GraSMech).

1.13 External developments related to EM

The research schools Engineering Mechanics (Solids) and J.M. Burgers Centre (Fluids) jointly compose the 3TU Research Centre of Fluid and Solid Mechanics. There is a long tradition of co-operation between the two research schools. The organizational structure of the research schools and their embedding in 3TU and the Netherlands is shown in the scheme below. At the international level, the two research schools are represented by the Netherlands Mechanics Committee (NMC), through which all formal communication with international scientific organisations (IUTAM, IACM, EUROMECH, etc.) flows. (should 4TU be mentioned as an external development?)

27

In 2014, the students enrolled in the joint EM-JMBC graduate programme (supported by NWO) started the PhD phase. Four students are presently working on their PhD projects, funded by NWO through the Excellence Track ‘Fluid and Solids Mechanics’. The research programme of the joint EM-JMBC graduate programme is composed of the core research areas in Fluid and Solid Mechanics. The Solids pillar in engineering mechanics is concerned with the description, analysis and optimization of the static and dynamic behaviour of materials, products and processes. Solid mechanics is at the heart of engineering mechanics, through which it plays a vital role in economy and society. The Fluids pillar is concerned with the description, analysis and optimization of fluid flows. It is at the heart of phenomena in our environment and is important for a multitude of industrial, biomedical and environmental processes. The interaction between fluids and solids in many engineering problems across the scales, constitutes a natural common part between both disciplines. Solid and Fluid Mechanics play a significant role in many areas of applications that are relevant for our economy, our society and the preservation of our environment. Solid and Fluid Mechanics are a core part of the educational programmes of a number of disciplines, e.g. Civil Engineering, Mechanical Engineering, Maritime Technology, Applied Physics, Aerospace Engineering, Applied Mathematics and Chemical Engineering. The financing of the Graduate Schools has changed considerably, and will be effective from 2015 onwards. As a result of the actions taken by SODOLA and in agreement with the VSNU, the boards of the universities have decided to provide financial support to the interuniversity graduate schools, like EM. For 2015, EM received a financial support of 50 kEuro from the Board of TU/e and and in kind support of 50 kEuro from the Department of Mechanical Engineering of TU/e. In 2014, the accreditation system of KNAW has come to an end. KNAW decided that it is no longer their responsibility to judge the scientific quality of the graduate schools, since this is largely embedded in the research evaluation of the different departments. On the other hand, the educational part is systematically more integrated in the local graduate programmes that each of the universities is developing. At present, discussions are ongoing to embed the quality mark of our graduate school in the 3TU context.

8. Short description of sub programmes related to research school EM

8.1 Non-linear dynamics of mechanical systems

The numerical and experimental study of non-linear and in particular non-smooth mechanical systems, such as systems with friction, impacts or other constraints are key activities in this sub-theme, and play an essential role in the modeling and analysis of advanced mechanical systems. The research on these phenomena is highly relevant in many engineering applications (friction in high-performance/high-precision systems, drill strings, high-speed milling, hybrid control

30

systems etc.). Numerical aspects are notably difficult, but are becoming more and more feasible with increasing computer power. Related to research theme “Structural Dynamics and Control”

8.2 (Structural) acoustics and noise control, optimization This sub-theme deals with various structural vibrations and the associated sound radiation. The focus is on the one hand on numerical/computational tools for acoustic models, and on the other hand on the experimental validation of those tools. Subsequently, both passive and active means for acoustic noise suppression are investigated. Several mechanical applications are used as benchmark examples, particularly tire–road noise. The development of tools for optimization is essential in the dynamic behavior of mechanical constructions. Related to research theme “Structural Dynamics and Control”

8.3 Vehicle dynamics, tire dynamics and control

Vehicle Energy Management Systems Topology Design Research is done on energy management of the complete power train, including the design trade-offs for hybrid vehicles with an internal combustion engine and an electromotor. Advanced model-based optimisation methods, like dynamic programming, are used for the off-line generation of optimal trajectories for the variables that dictate the energy supply from the combustion engine and/or the electromotor. We started a new research project on a hybrid truck. Vehicle Dynamics and Tyres The group is responsible for the research and teaching in vehicle dynamics. The research focuses on modeling, analysis and control of articulated vehicles, and modeling and analysis of vehicle tires. For the latter, extensive use is made of the flat plank tire tester in the Automotive Engineering Lab. The tire research is linked to the tire–road noise research referred to above. Related to research theme “Structural Dynamics and Control”

8.4 Mechanical Design and Vision The mechanical design group Construction and Mechanism is jointly headed with Prof.Dr.Ir. M. Steinbuch (Control Systems Technology). Dr.ir. P.C.J.N. Rosielle leads the activities in the C&M lab, which comprises on average 6 PhD students and about 10 MSc students. Focal point in the lab is the construction and design of advanced, novel mechanical systems. Related to research theme “Structural Dynamics and Control”

8.5 Systems Design Optimization Optimization methods to support systematic design and improvement of complex engineering systems are investigated. We concentrate on simulation-based design optimization in the context of manufacturing system and distribution centre networks, manufacturing machines, automotive systems, and micro-mechanical systems. Optimization methods and tools are being developed that can deal with typical governing characteristics such as: one or more computationally expensive computer simulation models in the loop, a mix of continuous and

31

discrete design variables, stochastic design variables and responses, and dynamic response behaviour. The development of techniques for approximation, meta-modelling, and lumped-parameter modelling that can be utilized in the optimization plays a central role in our research work. Furthermore, methods for design optimization of multidisciplinary and multi-level decomposed systems have our special interest. Related to research theme "Reliability and Optimization".

8.6 Control of Manufacturing Systems

In this sub programme two main streams can be considered. The first stream considers a class of manufacturing systems that can be approximately modelled by means of a continuous time fluid or flow model. For this approximate model, standard techniques from control theory can often be used to design controllers. As the manufacturing system has a discrete-event nature, a connection between the discrete event plant and the continuous time controller has to be developed. Continuous time signals have to be converted to discrete-events and measurements of discrete states need to be filtered for a better control performance. Currently available flow models often ignore variability, whereas queuing theory often considers only steady state behaviour. For that purpose new (mathematical) models need to be developed that include both variability and dynamics. It is clear that preferably these models should be suited for applying standard control theory in order to control these systems. The second stream considers the control of a network of servers through which many types of jobs flow, where it is assumed that servers require a setup time when switching between types. Such networks can be used to model complex communication, traffic or manufacturing systems. Related to research theme “Structural Dynamics and Control”

8.7 Nonlinear and hybrid dynamics

In this subprogram two main directions can be considered. First, general questions of nonlinear dynamics and control of mechanical systems including switched (hybrid) systems are studied. In recent years hybrid systems attracted a considerable attention due to possible applications in various fields of science and technology. The theory of hybrid systems is far from its completeness. Therefore it is of interest to further develop methods of analysis and design for such systems. In this research particular attention is drawn to the following two questions: analysis of oscillations in hybrid systems and formalization of some mathematical models of hybrid systems using the formal languages approach. The formal language used is Chi developed in the Systems Engineering group. The second direction of the research is to study applications for the theoretical results in the framework of systems engineering. Nowadays complex manufacturing machines contain discrete-event and continuous-time parts with interactions between the components. These interactions can result in nonlinear dynamical phenomena that should be taken into account during design and real-time control of the machine. This research theme has a strong relation with the topic Embedded Systems (within the Institute for Programming and Algorithmic). Related to research theme “Structural Dynamics and Control”

8. Short description of subprogrammes related to research school EM 8.1 Multi-scale Mechanics & Structure-Property Modelling

Upscaling from microstructure towards engineering properties requires advanced methods to extract relevant information from small scales and reveal the emergent behaviour at larger scales. The subprogramme targets this goal through the development of advanced homogenisation and multi-scale approaches, with a challenging application perspective. This subprogramme plays a central role in the research portfolio and can be identified in most of the research projects. Among the topics addressed are:

multi-scale mechanics as a link between materials science and materials engineering: homogenisation theories and models, study of the collective behaviour of small-scale processes, structure-property relations for complex microstructures

multi-scale methods for lattice networks, e.g. based on an extension of the quasi-continuum method (applied to paper and electronic textile)

discrete-continuum transitions: from dislocation pile-ups to crystal plasticity

diffusionless phase transformations, e.g. martensitic transformations as used in TRIP steels and metastable steels

microstructure evolution: substructuring, patterning, self-organisation etc.

time-dependent mechanics of thin films used for systems-in-foil

8.2 Computational and Experimental Micromechanics

The ultimate performance of materials and high-tech microsystems originates from the mechanics at underlying characteristic length scales, at which microstructures play an intrinsic role. To achieve a comprehensive understanding of these phenomena, this subprogramme focuses on the development of advanced physical models, computational tools and state-of-the-art experimental techniques to study them at the micro-scale. Attention is given to the mechanics of different engineering phenomena that emerge from the micro-scale on the one hand and from the mechanics of microsystems for small-scale applications on the other hand. Special emphasis is given on flexible electronics applications such as rollable displays and roll-to-roll production of solar cells and organic light emitting diodes (OLEDs). The latter have great technologic and commercial value, while stretchable electronics has the potential to open up a realm of possible applications in or around the human body, such as sensitive prosthetic skin or neuron- or retina-interfaces, e.g., for control of epileptic attacks. In these devices, the functionality is delivered by integration of, often brittle, micro-electronic components into a compliant, often polymer, substrate in order to make the device flexible or even stretchable. A primary concern is the reliability, because the systems can be highly fragile and are subjected to large thermo-mechanical loading during manufacture and use. Among the topics addressed are:

modelling of the mechanics and physics of micron-scaled plasticity: dislocation dynamics, -plasticity problems, thin films, crystal plasticity

computational-experimental analysis of the mechanics of single phases and metallic polycrystals, including size effects: grain boundaries, grain size effects, orientation-texture evolution, strain gradient effects, surface grain effects, strain path effects

mechanics of microsystems, including MEMS, NEMS and substructured materials, size dependent properties

thermo-mechanical and hygroscopic deformation of polymer films used as a substrate for

flexible electronics

delamination of the copper electronic wiring from the rubber substrate in stretchable

electronics

development of global digital image correlation (DIC) and integrated DIC to bridge the experimental work in the multi-scale lab to the modelling work done in parallel

8.3 Damage, Fracture and Reliability

The lifetime and reliability of engineering components and devices at all length scales are governed by damage and fracture of their constituting materials and interfaces. This subprogramme develops the in-depth understanding of all the related failure phenomena, and provides powerful models and computational solution strategies, together with dedicated integrated numerical-experimental identification methods. This subprogramme focuses on quasi-brittle damage, ductile damage and interface damage. Among the topics addressed are:

advanced 3D continuum ductile damage models

numerical methods to nucleate and propagate 3D cracks from continuum damage fields

interfacial failure in systems-in-package

mechanics of failure in fibrous networks (paper, paperboard, electronic textile)

40

thermo-shock failure in ceramics

functional damage as the result of dynamic overstraining in brain tissue

8.4 Free-Boundary & Interface Problems

Many problems in science and engineering are characterized by a connection between disparate subsystems at a common boundary or, similarly, by a fundamental change in the behavior of a single system across an infinitesimally thin layer. Typical examples are dynamic and thermodynamic interactions between a fluid and a solid, the interaction between two distinct immiscible fluids, or the intrusion of a tumor into healthy tissue. Generally, the interface between the subdomains constitutes a free-boundary, i.e., it is not fixed, but its motion is interconnected with the (initial-)boundary-value problems on the adjacent subdomains. Interface and free-boundary problems pose fundamental challenges to numerical simulation methods, on account of the resolution requirements at the interface and/or the complicated interdependence between the boundary-value problems and their domain of definition. A central theme in the research of the MEFD group is the development and analysis of advanced numerical techniques for interface and free-boundary problems.

8.5 Computational Fluid-Structure Interaction

A particularly important class of interface problems is fluid-structure interaction. In accordance with the reductionistic approach that pervades modern science, the fields of fluid and solid mechanics have historically developed independently. In fluid-structure interaction, a proper understanding of both subsystems is required. In addition, the interface between the fluid and the structure introduces additional complications, on account of its free-boundary character and the nontrivial interconnection between the fluid and structure subsystems via boundary conditions. The disparity between the fluid and structure subsystems moreover generally reflects in a wide range of length and time scales in the aggregated problem. An important focal point of the group pertains to the development and analysis of efficient iterative solution techniques and advanced finite-element discretization methods for strongly-coupled large-displacement fluid-structure-interaction problems.

8.6 Microsystems

Trends in Microsystems science and technology are the ongoing miniaturization, increased function integration, adaptivity to environmental conditions, interaction and merging with biological materials, and low-cost manufacturing approaches. The mission of the Microsystems group is to carry out excellent scientific and technologically driven research that contributes to these developments. The concrete objectives are to develop microsystems design approaches and out-of-cleanroom micro-manufacturing technologies that are rapid and flexible. These are applied to realize active mechanical control in micro-fluidics, to create and study cells and organs on chips, and to develop advanced microsystems applications in collaboration with industrial partners. The group’s research is carried out in 4 subprogrammes. (1) Micro-manufacturing technologies, which forms the heart of the group. The focus is on out-of-cleanroom technologies such as laser micro-manufacturing, soft lithography, on-foil processing, and printing. (2) Active control in microfluidics: We develop and apply micro-actuators, responsive surfaces, and magnetic bead actuation systems, to realize functions in microfluidic systems. (3) Cells and organs on a chip: In collaboration with biological, biomedical, and clinical groups, we apply our microsystems to studying and understanding the behavior of cells, tissues, and organs. This work is aimed at learning about health and disease, and eventually developing

41

novel therapies and medicines. (4) Microsystems applications, which can be found in many areas. In this subprogramme, we work with industrial partners to develop relevant technologies for these applications, in medical devices, high precision metrology, flexible electronics, and advanced sensors and actuators.

8. Short description of subprogrammes related to research school EM 8.1 Free-Boundary & Interface Problems

Many problems in science and engineering are characterized by a connection between disparate subsystems at a common boundary or, similarly, by a fundamental change in the behavior of a single system across an infinitesimally thin layer. Typical examples are dynamic and thermodynamic interactions between a fluid and a solid, the interaction between two distinct immiscible fluids, or the intrusion of a tumor into healthy tissue. Generally, the interface between the subdomains constitutes a free-boundary, i.e., it is not fixed, but its motion is interconnected with the (initial-)boundary-value problems on the adjacent subdomains. Interface and free-boundary problems pose fundamental challenges to numerical simulation methods, on account of the resolution requirements at the interface and/or the complicated interdependence between the boundary-value problems and their domain of definition. A central theme in the research of the MEFD group is the development and analysis of advanced numerical techniques for interface and free-boundary problems.

8.2 Computational Fluid-Structure Interaction

A particularly important class of interface problems is fluid-structure interaction. In accordance with the reductionistic approach that pervades modern science, the fields of fluid and solid mechanics have historically developed independently. In fluid-structure interaction, a proper understanding of both subsystems is required. In addition, the interface between the fluid and the structure introduces additional complications, on account of its free-boundary character and the nontrivial interconnection between the fluid and structure subsystems via boundary conditions. The disparity between the fluid and structure subsystems moreover generally reflects in a wide range of length and time scales in the aggregated problem. An important focal point of the group pertains to the development and analysis of efficient iterative solution techniques and advanced finite-element discretization methods for strongly-coupled large-displacement fluid-structure-interaction problems.

understanding how small-scale (microscopic) information affects the behaviour at larger (meso and macroscopic) scales. The activities focus on the development of robust and accurate computational models that follow the physics of the problem closely, and obey rigorous mathematical principles characterizing the separate scales and their coupling.

8.2 Multi-physics modelling of structures and materials:

Modelling processes characterized by the interactive phenomena originating from multiple physical processes, such as thermo-mechanical processes that define the failure response of metals under varying temperatures, or thermal-chemical-mechanical processes that define the fracture behaviour of brittle coating systems under thermal oxidation.

8.3 Morphology and topology optimization: Studying structural shape, size, phase distribution and texture at the microscale (morphology) and structural shape and space at the macroscale (topology) for optimizing the mechanical properties and interactions of materials and structures.

8. Short description of sub programmes related to research school EM

8.1 Scientific Computing

The main emphasis in this program is on analysis and numerical simulation of problems arising

in technology. Research is often induced by specific applications, yet being seen as part of a

larger area where mathematical tools and in particular numerical methods can be applied.

Hence both fundamental (numerical) research and applying the results to specific applications

are typical for Scientific Computing. The following areas specify the actual research:

8.1.1 Ordinary Differential Equations and DAE

Problems that exhibit an evolutionary character will result in ODE after spatial discretization.

Moreover problems in control and mechanics often lead to such equations more directly. Quite

often they are coupled with some (algebraic) constraint equations, resulting in DAE. Matters like

stability and accuracy of numerical methods still provide for important questions. Co-operation

exists with the TU/e-department of Mechanical Engineering.

Related to research theme “Computational Mechanics”.

8.1.2 Large Scale System Solving

In solving partial differential equations numerically, one encounters complex larger (non) linear

systems which exhibit a sparsity structure. In order to be able to solve them one need special

iterative solvers, like multigrid. In this area one can also often employ parallel architectures

fruitfully. Co-operation exists with TNO-TPD and the TU/e-department of Computer Science.

Related to research theme “Computational Mechanics”.

8.1.3 Modelling and Finite Element Applications

Although there exists a variety of FEM packages, it is often necessary to tailor methods for

specific problems. Further development and improving them is a core activity. A particular

aspect is the visualization, which is increasingly important due to the ever increasing complexity

of problems to be solved.

Related to research theme “Computational Mechanics”.

66

8.1.4 Boundary Element Methods and Approximation

The research on BEM is concentrating on the quality of approximations of non-homogeneous

problems. In particular it is investigated how various basic approximation methods like radial

basis functions lead to convergence and therefore efficient methods. Related to research theme

“Computational Mechanics”.

8.1.5 Wave Analysis for lithography

Analysis of diffraction gratings that are used to determine the position of a wafer in a wafer

stepper. Numerical methods like RCWA (Rigorous Coupled-Wave Analysis) are investigated to

solve these equations in a stable and accurate way. New software tools will be developed for

sensors that have the improved RCWA algorithm incorporated.

Related to research theme “Computational Mechanics”.

8.2 Applied Analysis

The main emphasis in this program is on mathematical analysis of technological problems.

Research is often fostered by specific applications, after which it may trigger more fundamental,

and thus more generally applicable research:

8.2.1 Mathematical Methods in Continuum Physics

Slow viscous flow of polymeric melts: considered is the mathematical simulation of manufacturing processes for polymers such as fiber spinning, extrusion and injection moulding. These processes are considered as slow viscous (Stokes-) flows. The polymeric melts are described as nonlinear thermoviscoelastic fluids. Analytical and numerical evaluation of the resulting system of partial differential equations is looked for.

Analysis of dislocation structures in crystal lattices: Dislocations are the carriers of microscopic plastic deformation. In this project we develop rigorous mathematical methods for the upscaling of a large number of such dislocations, with the aim of constructing a rigorous derivation of mesoscopic crystal-plasticity models.

8.2.2 Fundamental Analysis of (Non-Linear) Evolution Problems

Our research in functional analysis is concentrated on evolution equations. An inspiring source

of inspiration are non-linear evolution equations arising from free boundary value problems in

quasi-stationary fluid dynamics (Stokes flow, Hele-Shaw flow, polymer flow).

8.2.3 Industrial Mathematics

Problems and questions from industry.

All subprograms within 8.2 are related to research theme “Mechanics of Materials”.

8. Short description of subprogrammes related to research school EM 8.1 Structural tailoring, design and optimization

The demands of high-performance, structural integrity, durability, low weight, and minimum cost pose an important challenge to structural designers. New materials may assist in satisfying some of these demands, but at the same time give rise to significant new problems for the designers. Furthermore the structural design can no longer be seen as an isolated activity, but must play its part in a multi-disciplinary approach to the design of the aircraft or spacecraft as a whole. The traditional approach to design is no longer adequate unless it can be supplemented by a numerical, computer-based approach in which the trade-off between conflicting design requirements can be quantified, and many more alternatives evaluated. Optimization plays an important role in this process, by providing a tool to identify the active design constraints and to steer the design towards some required goal such as minimum weight or cost. The goal of the research efforts in this area is the development of efficient and robust design and optimization tools for a variety of challenging structural design problems, which meet the needs that industry is facing.

The following topics are included in this sub-program:

Development of design and optimization procedures for specific structural design problems; Theoretical optimization including multi-level procedures and optimization of structural shape and layout;

74

Tailoring of advanced fiber-reinforced composite structures; Design and optimization of actively sensed and actuated structures. 8.2 Stability of thin-walled structures

In modern designs, which are often obtained by use of one of the structural optimization codes and which may be of new high strength materials such as advanced composites, structural response is often dictated by the stability and vibration behavior. This is due to the drive for achieving lightweight structures which result in thin-walled constructions. Such structures are sensitive to imperfections and display nonlinear response characteristics. This implies the need to investigate and understand the response characteristics of thin-walled structures under different loading conditions by carrying out extensive numerical calculation and/or experimental validation. A key issue is the development of fast and accurate analysis capabilities for thin-walled structures, incorporating all the theoretical knowledge accumulated in the last decades through intensive research in the aerospace, nuclear, and offshore fields, and making efficient use of the currently available interactive and (super-) computing facilities. Part of the ongoing thin-walled structures research is therefore concerned with the buckling, post-buckling and dynamic stability behavior of shells. The goal of the research efforts in this area is the availability of improved design criteria and the necessary analysis tools. The following topics are included in this sub-program:

Theoretical, numerical, and experimental studies of the collapse behavior and nonlinear behavior of composite panels and shells under static and dynamic loading; Development of an International Imperfection Data Bank and DISDECO (Delft Interactive Shell DEsign COde); Development of efficient semi-analytical and Finite Element based tools (reduced-basis methods) for the nonlinear analysis of slender and thin-walled composite structures. 8.3 Advanced computational methods for structural and functional materials

A wide variety of challenging problems in aerospace engineering cannot be satisfactorily solved using the traditional finite element method based on Lagrange polynomials. Limitations of the traditional FEM are related to its high computational cost in complex systems and/or its inability to model relevant features in the problems. The sub-program on advanced computational methods focuses on the development of novel computational methodologies intended to address the shortcomings of the traditional FEM. One main thrust in this program pertains to the area of Isogeometric Analysis, which provides a seamless connection between objects created in CAD software and the corresponding analysis. This computational approach streamlines the design process and supports the activities in other research sub-programs. A second focus point is the development of computationally-efficient Multiscale Analysis algorithms that relate the microscopic behavior of materials and systems to their effective (macroscopic) response. Both concurrent and hierarchical multiscale approaches are used for advanced material modelling and solution of coupled problems. The following topics are included in this sub-program:

Isogeometric analysis and design of composite turbine blades and shells

Isogeometric analysis of fluid-structure problems

Multiscale simulations of multiphase steels

Lifetime predictions of self-healing thermal barrier coatings used in aeroengines

8.4 Lightweight composite structures

Increased use of composite materials in aerospace, automobile, shipping, and civil engineering structures has revealed several areas where improved understanding of the performance of these structures under mechanical loading is required in order to decrease their weight further or tune their performance more accurately to specific requirements. Relevant requirements are frequency response, crash absorption capability, and geometric stability under thermomechanical loads. Work is continuing in the areas of damage tolerance and fatigue of composite structures. Quasi-static finite element-based modeling of impact of monolithic laminates and grid stiffened structures showed that a combination of failure criteria for fiber failure and a critical energy release rate calculation for delamination in a progressive failure model gives good accuracy in the extent and type of damage caused during low speed impact. Different models are used for the residual stiffness and strength of the damaged material. The method is extended to compression after impact and comparison with published results shows very good agreement for most quasi-isotropic laminates. The following topics are included in this sub-program:

Use of advanced physics-based failure criteria to predict onset of failure during impact

Progressive failure with continuous updating of strength and stiffness of fibers and matrix for impact damage and fatigue analysis

Use of failure criterion in finite element modeling of the impact event in grid-stiffened structures

Experimental verification of analytical predictions for compressive failure of composite grid-stiffened structures with damage.

Use of degree of bonding to predict the quality of laminates produced using automated manufacturing techniques in composites with FEM

Experimental validation of interlaminar shear strength of laminates produced using automated tape laying

8.5 Smart structures

Smart Structures may very well lead the way to the next breakthrough and major technological advancements in aerospace. Applying smart structures to aerospace engineering requires a new way of thinking in terms of integration as well as multidisciplinarity and multifunctionality. The focus of the smart structures research at ASCM is dedicated towards solving the design challenge that is posed by smart structures because of their multidisciplinarity and multifunctionality. Furthermore research efforts are dedicated towards practical solutions for smart structures. The goal is to develop concepts starting from initial ideas all the way to proof of concept in a realistic environment like a wind tunnel of a large-scale UAV. The following topics are included in this sub-program:

Numerical aeroelastic analysis and design of smart structures

Concept development and hardware of morphing structures

Wind tunnel experiment of smart structures

Active control and performance optimisation using smart structures

8. Short description of subprogrammes related to research school EM

8.1 Structural Optimization and Mechanics

For the case of Micro-Electrical-Mechanical Systems (MEMS) and high-tech applications, the interaction between mechanics and other domains of physics becomes critical. For mechanical problems related with engineering materials, different length scales need to be taken into account with various multi-scale approaches. Because of these aspects, the analysis of practical problems usually takes a tremendous effort. Therefore, further development of efficient, multidisciplinary, multi-scale numerical modelling techniques is required. It is also important to increase the computational efficiency of numerical techniques by smart choices of model order reduction without compromising the desired level of accuracy. These techniques should be tailored for high-performance computer architectures.

Vital to the numerical techniques aforementioned is the finite element method (FEM), which has become the de facto methodology for the analysis of problems in computational solid mechanics. The activities being developed at SOM not only make use of the FEM for solving challenging problems, but also involve developments to improve the numerical techniques themselves. In particular, finite element formulations of the Generalized/eXtended (GFEM/XFEM) type have the spotlight nowadays because of their ability to deal with complex geometries with very simple and structured finite element meshes. Decoupling the problem geometry from the mesh it is solved upon brings extra flexibility that could be exploited in the search for optimal designs.

Once numerical techniques are incorporated in a design process, for which often many intermediate designs and corresponding design sensitivities must be evaluated, the efficiency requirements are even more demanding. This holds for a design process in which intermediate designs are evaluated "manually", but becomes more important for (partially) automated optimization processes. Improvement of structural optimization techniques cannot be achieved independently from new developments in Computational Mechanics. Only a close integration of structural optimization techniques and numerical analysis strategies can yield the most efficient design tools. Clearly, manufacturing constraints impose additional challenges on the optimization. Within this theme, the fundamentals for modelling, analysis, design sensitivities and optimization of structures will be developed. The focus will be on the multidisciplinary links between these aspects. Furthermore, new developments will be translated in prototype designs, ready for laboratory testing and ultimately made available for

87

day-to-day practice. For this purpose we are collaborating with more application-oriented groups and companies.

8.2 Dynamic Behavior of Mechanical Systems

The design of current and future mechanical systems across different space/time scales becomes more challenging as new material developments, manufacturing technologies and design techniques make the systems lighter, more complex, more flexible and multi-functional. The challenge is mainly associated with the activation of nonlinearities which can give rise to a variety of phenomena that are not typical of linear systems: nonlinear modal interactions, transfers of energy from low to very high frequencies (situation which can become critical in complex micro-nano systems architectures), bifurcations, parametric multiplicative instabilities, subcritical behaviors, sub/superharmonic resonances, saturation, etc.

The aim of the Engineering Dynamics group is to develop studies addressing open problems in nonlinear dynamics with ground-breaking innovations in experimental, theoretical and numerical investigation. In particular, the goal is to put multi-scale nonlinear dynamical systems under a powerful microscope and pull as much as possible in full, three-dimensional formulations to unfold subtle behaviors, understand and frame them in unified theories and pave the way to their exploitation for enhanced mechanical designs. These are carried out by (i) developing innovative numerical codes based on reduced-order models together with analytical dynamics tools such as perturbation methods coupled with modern path following and bifurcation techniques, (ii) developing sophisticated measuring systems and experimental procedures to validate numerical codes, and observe complex dynamics.

The stated goals call for new tools or innovative modifications of existing tools to resolve the various time and space scales that can coexist in multi-scale nonlinear dynamical systems. Moreover, the nonlinear dynamical phenomenology is not simply investigated to avoid it during systems operations, but to integrally embed it into the design process so as to drastically improve controllability in new passive/active vibration systems architectures, sensitivity in sensing systems such as mass, and pressure sensing, actuability in actuator systems, and observability in damage detection systems.

8. Short description of sub programmes related to research school EM 8.1 Structural Dynamics and Control (Prof.dr.ir. A. de Boer, Prof.dr.ir. T. Tinga)

The research in this EM subprogramme is directed towards:

Structural dynamics, involving rotating components in machinery and optimisation and actuation of vibrating structures.

Fluid-structure interaction and acoustics, with emphasis on thermal viscous wave propagation and acousto-elastic coupling and the accompanying noise production.

Dynamics Based Maintenance, with focus on vibration based structural health monitoring and physical model based predictive maintenance.

The research of the group aims at generation of new, fundamental knowledge by combining numerical and experimental techniques. Based on this knowledge engineering tools are validated and made ready for application in key industrial problems. A characteristic feature of all themes is the innovative use of advanced numerical simulation methods in a design environment. Crucial information that is difficult or even impossible to obtain from experiments is added through numerical models. Current topics are:

Structural Dynamics (Prof.dr.ir. A. de Boer) (1) Optimization of Dynamic Systems with emphasis on model reduction methods.

Optimization problems concerning complex structures with many design variables may entail an unacceptable computational cost. This problem can be reduced considerably with a multi-level approach; a structure consisting of several components is optimized as a whole (global) as well as on component level. This year a new PhD (Farshad Farzan Nasab) has

109

been started on this topic in the framework of the Dutch TAPAS 2 (Thermoplastic Affordable Primary Aircraft Structure) programme.

(2) Rotor Dynamics and Multi body dynamics Rotating parts in machinery are sources of vibrations and can therefore affect the life time of the rotating part itself and the whole machine drastically. The tendency to optimize the functional performance of structures results in modern designs which often exhibit a minimal weight and very tight safety factors. In 2015 research has been carried out (by PhD P. Le) on performance improvement of micro-reaction wheels. This is done in collaboration with Moog Bradford and TU/e department of Applied Physics. Further in 2014 a new project has been started with the goal to develop methods to couple flexible multi body dynamics with other physical phenomena such as hydraulics and acoustics. In 2015 this research (carried out by PhD J. Schilder) focussed on the coupling of ship movement and water on the one hand and rotating blades with air on the other hand.

Fluid-structure interaction (FSI) and acoustics (Prof.dr.ir. A. de Boer) (1) Viscothermal wave propagation

Together with the Thermal Mechanics group of the University of Twente research is carried out on Thermo-acoustic heat pumps. PhD student Anne de Jong defended the research he did on this topic on July the 3rd 2015 succesfully.

(2) Sound-absorbing materials.

A closely related part of the FSI research program, involves the development of methods and models concerning sound-absorbing materials. Marieke Bezemer focus on the angle dependence of the absorption coefficient for road pavement. In 2015 she used her model for porous pavement for the design of silent pavement. The pavement was constructed and tested. The results are now analysed.

(3) Efficient analysis and measuring methods for source localisation

(4) Thermo-acoustic structural interaction

In june 2015 Farnaz Tajderi started research on the development of flat acoustic source structures driven by multiple controlled energy efficient actuators that can be used to realize a sound source capable of generating low frequency sound to be useful for sound generation and active noise control applications as the secondary source.

Dynamics Based Maintenance (prof.dr.ir. T. Tinga) (1) Structural Health Monitoring (SHM)

Several research projects are conducted on this topic, some of which are in collaboration with Production Technology, Prof.dr.ir. R. Akkerman (see chapter 11 ‘Production Technology’ for more details). Jason Hwang (NLR) started a part-time PhD project, focusing on the development of performance indicators for SHM methods. Within the European WIBRATE project Andrea Sanchez Ramirez further developed her strategy for wireless vibration monitoring of (rotating) systems and complete structures. Neda Mostafa started as a PhD in the H2020 project DestinationRail, developing SHM methods for railway bridges. Hector Hernandez is working in the TTIW Wetsus Water distribution program - InnoWator. The research program of the Technological Top Institute Water, financed by the Dutch government and Dutch industry, focuses on improving the water distribution networks. The

110

InnoWater project, executed by, focuses on ultrasonic measuring technologies to measure the dynamic response of a water pipe during service. The dynamic response provides insight in the age of the material and the resulting remaining life time. This project is in collaboration with Production Technology, Prof.dr.ir. R. Akkerman. See chapter 13 ‘Production Technology’ for more details

(2) Predictive Maintenance

In several projects predictive maintenance methods are developed, mostly focusing on a physical model based approach. By modelling the relevant failure mechanisms, monitored loads on the systems can be used to predict the time to failure and optimize the maintenance program. Filippos Amoiralis, PhD student in the Dinalog funded Maselma project, developed models for maritime systems, specifically focusing on marine diesel engines. Annemieke Meghoe started working on similar methods predicting railway time to failure in a project funded by Strukton. The NWO funded SINTAS project on the impact of additive manufacturing (3D printing) on maintenance decisions and logistic processes was started. Laura Cordova, one of the three PhD students in this project, investigates the durability and life time aspects of parts produced by different AM techniques, which is used as input for the maintenance and logistics optimization models in the other two work packages.

8.2 Computational and Experimental Mechanics (Prof.dr.ir. A.H. van den Boogaard)

The research in this EM subprogramme is directed towards Nonlinear Solid Mechanics. The mission of the Chair Nonlinear Solid Mechanics (NSM) is to develop and experimentally validate advanced numerical methods for the accurate simulation of nonlinear mechanical behaviour, in order to support the industrial needs for optimal and efficient methods for designing and manufacturing of parts and products. The main application areas of the chair are Material Forming Processes

Mechanical behaviour of biological tissues Increased demands for accurate and computationally efficient simulations require that a number of topics have to be addressed:

Improved macroscopic material models Accurate constitutive equations are required in order to predict the final shape of a work piece after forming and subsequent spring back and its subsequent service properties. In particular the effect of the initial and evolving anisotropy, the changes in loading path as present in multi-stage forming processes, the strain rate dependency, the consequences of temperature changes in warm forming processes and the effects of annealing periods between successive forming steps have to be properly accounted for, including the effects of phase transformations. Nonlinear material behaviour in biological materials is related to large visco-elastic deformations in fibrous materials or to fracture phenomena of hard materials like bone. Both types of materials show significant anisotropy. Material properties are commonly determined from uni-axial tensile experiments, but the deformation mode in forming is usually 3-dimensional and non-proportional. Therefore, constitutive models need to be able to consider arbitrary 3D loading paths. Although macroscopic models are required for full-process simulations (regarding CPU-time), development of the models benefits from considering micro-structural evolution and therefore microscopic

111

models are also investigated. Examples of this approach are the modelling of damage and thermal conduction in carbon foam press fittings and the anelastic deformation of steel at unloading. In order to validate material models under multiaxial stress state and arbitrary deformation paths, a biaxial test facility is available. The test facility allows for biaxial loading under simultaneous bi-directional shear and tension/compression of sheet material, including strain path changes and strain rate changes.

Advanced solution algorithms The focus of the sub-programme ‘solution algorithms’ is on efficiency. I.e. increase accuracy of calculations and/or reduction of calculation time. For steady-state type of processes, like rolling and extrusion, the ALE method is developed in this group, where the relevant deformation zone can be modelled in isolation of the non-deforming part of billet or product. For use in optimization or control algorithms, fast simulations are required and Reduced Order Modelling techniques are investigated. Finally, full process chain simulation requires the numerically efficient coupling of several forming stages, often with their own modelling details.

Joining, surfaces, contact and friction Similar as for material modelling, also the surface behaviour must be simulated with high accuracy. This field considers bonding and friction in relation to surface pressure, relative velocities, roughness, temperature et cetera. In a project jointly with the Surface Technology group a friction model that describes the effects of the surface topology on the micro scale in FE simulations on the macro scale was realized. The algorithm incorporating the model is applicable to full-scale automotive sheet metal forming simulations. Currently, this model is extended for use with coated steel and for use in hot stamping. In another project spot welding of press hardened boron steel is investigated. The influence of thermomechanical history in the heat affected zone on the strength is modelled in detail and subsequently transformed into a simplified model for full car-body analysis.

Optimization and control When processes can be modelled accurately enough, the logical next step is to optimize processes by automatic numerical optimization. If robustness is not considered in optimization of forming processes, the resulting optimum is usually critical with respect to constraints. Arbitrary safety margins may be either insufficient or not fully exploit the full potential of the material; therefore the optimization model should include variability in the material properties, tool geometries and process conditions. A methodology for the prediction of the mean and standard deviation in sheet metal forming was developed and coupled to optimization of a process while reaching a required robustness. When tolerances are reduced, a sufficiently robust process setting cannot be found and the process must be actively controlled, based on a model of the process. This model-based control requires extremely fast predictive models, to correct deviations that are measured in-line. Current research focusses on fast interpretation of process data to account for material and process scatter.

8. Short description of sub programmes related to research school EM The subject of research of the surface technology and tribology group is the interaction between surfaces. The nature of the interaction between the opposing surfaces depends on the operational conditions and therefore the physics describing the interaction is for each situation different. In the figure below the interaction between surfaces is in general depicted. The system researched is represented by envelope I, envelope II (corrosion) is subject within the courses given by the surface technology and tribology group. Based on validated models design “tools” are developed for reliable and accurate prediction of friction and wear. The main subjects are I) High Tech Systems and Energy, II) Health and III) Reliability and Durability (maintenance).

Fig. Surface Technology and Tribology. Research platforms and themes, I) High Tech Systems and Energy, II) Health and III) Reliability and Durability.

8.1 High Tech Systems and Energy

The theme high tech systems deals with the realization of contacts in mechanical systems operating in extreme environments. Examples are low temperature, high temperature as well as low pressure (e.g. vacuum systems) and high pressure environments. Although these contact may appear different, there are many similarities. In order to realize such contacts, ceramics, polymers, coatings and surface treatments are required instead of metallic surfaces lubricated with lubricants. If contacts are lubricated, typically solid lubricants are used. Further, in all cases, the environment is significantly influencing the tribological behaviour. The research is performed by a combination of model development and experiments in these extreme environments. Examples, of topics studied in the theme are solid lubrication at high temperatures, bonding in composites and positioning in vacuum systems. A big societal theme which gets a lot of attention nowadays is to make energy available in a sustainable way using sources like wind and sun. However, an efficient use of the available energy does not receive the necessary attention. Within this theme the focus is on the reduction of energy loss. This loss can be the result of frictional losses and/or the waste of components (materials) in mechanical systems. The systems studied are mainly liquid lubricated systems which can be for instance found in the transport industry (automotive and railway) and metal forming industry.

123

8.2 Health

The growth of engineering activities for health care, sports and medical applications has initiated the development of innovative simulation and visualization techniques. This area of industry is e.g. searching for tools that can predict the human perception of products as a function of design optimization parameters. Such tools would also reduce the need for extensive panel testing or for animal testing. Friction and wear in human – product interfaces is considered to be of high importance for such an approach. Successful research requires knowledge on tribology, surface engineering, materials technology, physiology and dermatology, with a clear focus on industrial design. Research on the tribology needed for innovation in engineering of human - product interactions is structured in this theme by combined PhD projects focused on : 1) Skin Friction Fundamentals; 2) Sensing & Control of Friction; and 3 ) Bio Inspired Interfaces. Skin tribology requires in vivo, subject and anatomical location specific test methods, that are developed within research projects. Current predictive friction models can only partially be applied to predict in vivo skin friction. The reason for this is found in limited understanding of contact mechanics at asperity level of product - skin interactions. A recently developed model gives the building blocks for enhanced understanding of friction at micro scale. Only largely simplified power law based equations are currently available as general engineering tools. Surface texturing and polymer brush coatings are promising directions as they provide way and means to tailor friction in sliding contacts without the need of major changes to the product.

8.3 Reliability and Durability

Within the theme durability and reliability the developed knowledge should lead to the prediction and/or extension of maintenance intervals. Initially, the research is directed towards the development of models for wear and lubrication. Physical models make it possible to predict the performance under conditions which cannot be tested, either because of unacceptable high costs, or because of unacceptable duration. Wear models predict the transition from mild to severe wear and wear rates as a function of the operating conditions. Applications are wheel-rail contact, camshaft follower contacts, gears, rolling bearings and plain bearings. The wear models combine the response of the material and lubricant on severe operating conditions. The lubrication models are developed to predict re-lubrication intervals. This work is primarily done for lubricating greases. Much work is done on understanding and modeling the rheology of grease and on the development of film thickness models for grease lubrication. The lubrication and wear models should be integrated into durability models which can be used to calculate the reliability or life-time of equipment. Special attention will be paid to so-called “early failures”, i.e. failures that do not fit into the failure distribution function corresponding to the expected failure mode. In the future, the interaction between the tribological phenomena in the various elements of a machine in combination with dynamic behaviour (varying operating conditions, start-stops etc.) on reliability and durability will be studied.

8. Short description of subprogrammes related to research school EM Research in the Production Technology group addresses the technical issues of new products and new processes. The group focuses on the optimisation of both the manufacturing process and the product performance. ‘Processing’ and ‘Product performance’ of lightweight materials in structural applications characterise the main research themes of the Production Technology group. In our view processing and performance can be optimised after thorough analysis and modelling in combination with a firm experimental programme. The experiments identify the operating mechanisms, establish relevant material property data for the modelling and provide data to test the accuracy of the models proposed. An integral approach is pursued, taking into account the interrelations between the geometric design, the production process and the material properties. The Thermoplastic composites Research Center TPRC, hosted by the group of Production Technology, continued to grow with additional members, leading to a gradual increase in research and number of PhD students. An EU funded HORIZON-2020 project “ambliFibre” has been started since September 2015. The mission of ambliFibre is to develop and validate the first model-based laser-assisted tape winding system for the manufacturing of tubular thermoplastic FRP parts. Production Technology is leading the Work Package 3 in which multi-physics based numerical process models will be developed for inline automated process control and virtual simulations of the laser assisted tape winding process of thermoplastic composites.

8.1 Automated Composites Manufacturing The first research theme is concerned with the cost-effective application of advanced continuous fibre reinforced composites. The breakthrough of this type of materials in various applications has occurred to a smaller extent than might have been expected, mainly due to their high costs of manufacturing. Thermoplastic composites in particular have the potential to overcome these hurdles. In general, research in the PT group starts from a thorough analysis of the deformation and flow mechanisms involved during manufacturing and the modelling of these mechanisms. Design tools are developed to support the production of composite structures with modern techniques. The aim of these design tools is mostly to optimise the processing conditions in order to obtain a composite component having a prescribed shape or combination of materials properties.

High Precision Composites Moulding Forming simulations are needed to shorten the development time of novel composite products. This requires better constitutive models, better characterisation techniques and dedicated model

131

implementation. In this context, Ir. Van Ravenhorst continued the development of a circular braiding process simulation model to predict the fibre orientation and -distribution on arbitrary mandrels. He attempted to describe the non-axisymmetrical biaxial braiding process including yarn-to-yarn interaction including friction using a numerical derivative-free non-smooth non-linearly constrained non-linear optimization method. Within TPRC, Ir. Kok continued his PhD research on the laser assisted tape placement process, looking specifically into the generation of defects (porosities, and their effect on the interlaminar bonding) during fast tape deposition; with the aim to optimise the process and the resulting material performance. Ir. Wolthuizen continued his research (also funded by TPRC) on a multilayered shell element for composites forming. A procedure was developed to resolve the intra-ply shear locking phenomenon in triangular elements with extreme anisotropy. The procedure will be implemented in a finite element code suited for large scale computations. Dr Baran, who graduated in 2014, won the “ESAFORM PhD Prize for Industrial Research 2015” as well as the “Young Scientist Award” from the Danish Plastics Federation (Denmark) for his research on the pultrusion process. Within the PT group, he is mainly working on the numerical modelling of composite manufacturing processes with a focus on predicting the process induced residual stresses. Efficient wind turbine blade manufacturing Ir. Sybren Jansma has been developing new production techniques to produce (parts of) a thermoset windmill blade in particular the tip section. This is a necessary step to introduce new concepts for splitting blades which are beneficial for large wind turbines. Moreover, he has also been investigating the methods to connect the tip section to the main part of a wind turbine blade. This research concerns detailing and testing connection types from macro to micro level. Stamp forming process Within TPRC, Ir. Tjitse Slange started with his PhD research on the stamp forming of tailored thermoplastic composite blanks, with a focus on the evolution of consolidation quality (void content, crystallinity, bond strength) during the stamp forming process. The aim is to optimize the process and improve final part quality.

8.2 Performance of Advanced Materials The second research theme involves a better understanding of the mechanics of new materials, focusing on the physical properties of the component and taking into account the production process used. An increasing range of properties is being considered, from thermo-mechanical properties such as stiffness and structural integrity, to optical and electromagnetic properties on the short and the long term. Materials with ‘added functionality’ (e.g. composites with integrated sensors and actuators or even self-healing capacity) receive growing interest. The current research projects in this theme are:

recycling of thermoplastic composites

friction surface cladding of light metals

thermoplastic composite joints

sustainable materials

Recycling of thermoplastic composites Ir. Guillaume Vincent started to work on the recycling of thermoplastic composites within TPRC. Thermoplastic composites are inherently easier to recycle than their thermoset counterparts, since both the fibre and matrix material can be recycled and fibre reclamation is not required. Within this project, the recycling loop of post-industrial thermoplastic composite waste will be studied, from shredding to re-processing. The main objective is to determine processing conditions of the total recycling loop from cutting to re-manufacturing, that lead to maximal cost effectiveness and minimal

132

environmental impact.

Friction Surface Cladding Friction surface cladding (FSC) is a solid state process to deposit thin metallic layers on substrates. It is primarily developed to improve the corrosion resistance of the workpiece surface, as described by Dr. van der Stelt in his PhD thesis who graduated from the PT group in 2014. The process parameters involved in FSC are currently being studied by S. Liu MSc. The process window has been determined for different cladding tools via an experimental approach. This cladding process can also be extended to additive manufacturing like 3D printing in the solid state and more material combinations, as being studied by MSc. I. Yussof. Thermoplastic Composite Joints F. Sacchetti continued his research on the characterisation of the bonding strength, examining the effect of different manufacturing processes on the joint performance. such as ultrasonic welding, autoclave consolidation and press consolidation. The scope of this project is to establish mechanical testing procedures to characterize the performance of different fusion bonding methods for thermoplastic composites materials. Existing and novel testing methodologies will be investigated for their applicability to characterize joint performance. Proper selection of a testing technique, however, requires a good understanding of all factors affecting the measured property. Apart from intimate contact development and polymer diffusion, these factors may include interface architecture, polymer crystallinity and surface pre-treatment methods. The important factors governing the measured results will be identified through a combination of comprehensive analytical and experimental work. Sustainable materials Sustainable and bio-based materials are getting more and more attraction. Iqbal Rasheed MSc continued his work on compression moulding of woven thermoplastic composite flakes, that may originate from production waste during composites processing or end-of-life scrap, now with TPRC funding. Experimental and theoretical studies were performed to understand the material behaviour in terms of processing and mechanical performance. This enables to improve the understanding and control of the compression moulding process. A full-scale part was manufactured with integrated features like ribs, joggles, as well as moulded holes and thickness transitions to demonstrate the capabilities of the material and the developed process. With his work, Iqbal won the “Outstanding Paper Award”, CAMX –The Composites and Advanced Materials Expo”, 2015.

All activities within the programme are related to the research theme “Computational and Experimental Mechanics”.

8.1 Multiscale simulation techniques

The discrete element method (DEM) is used extensively for the simulation of granular materials and in powder technology. Averaging or coarse graining (CG) techniques, also referred to as the micro–macro transition, are applied to the particle data from DEM simulations to extract bulk continuum fields such as density, velocity and stress, which are important for the design of a great majority of engineering applications. The major aim of this work is to answer the question about temporal and spatial averaging scales, and what is their influence on the micro–macro projected continuum fields. Those scale often very between different engineering processes. Final goal is to enhance the way of coupling between particle and continuum methods for multi-scale modeling, not only relying on a future increase of available computing power, but also keeping massive parallelization in mind. At the same time, hierarchical hash tables and multilevel grids for efficient simulation of poly-disperse systems and FEM/DEM coupling for fluid particle interaction problems e.g. porous media, fluidized beds is being developed in the MSM group.

8.2 Bridging the gap between particulate systems and continuum theory

Particulate systems can be found in our daily life, as sand on the beach and as food - like muesli - in the kitchen. They are everywhere in nature and constitute over 75% of all raw material to industry. The particles in these materials interact and move together, which leads to unpredictable segregation phenomena - like in the muesli, where the large parts float on the top. Sometimes this also leads to fatal phenomena like landslides or snow-avalanches, which must be avoided or at least predicted. These particles can only be understood and predicted by using modern particle models and computer-programs, but continuum theory is used in engineering and design for almost all applications, because there are too many particles involved. Therefore, both pictures have to be combined and the gap between them has to be bridged in order to avoid problems, improve safety and enhance many the products we use every day.The VICI project is almost ended and great results have been achieved on the challenge bridging the gap between particles and continuous systems – where especially, stochastic and mesoscale methods are essential pillars supporting the bridge.

8.3 Wave propagation applied to gas/oil exploration, production, and processing

The project goal is to apply advanced computational science tools to predict flow, permeability, and nonlinear wave propagation through gas/oil-reservoirs to enhance efficient exploration, evaluation, and production – as well as energy efficient processing and storage. The multi-scale

140

approach starts at the disordered grain/particle/porous-structure scale, cross-couples the high-pressure multi-phase fluid thermochemistry and -mechanics, and targets at the larger, seismic/reservoir length-scales. As motivation, in underground exploration of energy-related resources, only low frequency modes are visible, i.e. small length scales disturb transport and wave propagation. The challenge is to model this multi-scale problem, which requires innovation in computational science for understanding and interpreting non-linear wave-propagation.

8.4 Multiscale Analysis of Particle Processes Despite their significance, many industrial particulate processes display unpredictable behaviour due to both their multiscale nature and the coexistence of different phases: this leads to undesirable losses in resources, energy, money and time. Considerable progress can be achieved using multiscale analysis and modelling to provide both visual and quantitative details of the dynamics of multiphase particulate systems. However, immature predictive capabilities, together with a lack of expertise and education in this developing field, hinder the adoption of these technologies. In order to address this skills gap, a new EU-ITN network, T-MAPPP, brings together 15 leading European organizations in their respective fields, including 10 industrial companies and stakeholders ranging from agriculture/food processing, consumer/personal care, chemicals/pharmaceuticals to software and equipment manufacture, to foster and develop a pool of ESRs and ERs who can transform multiscale analysis and modelling from an exciting scientific tool into a widely adopted industrial method.

8.4.1 Constitutive modeling of (adhesive) anisotropic granular solids Dense granular materials behave differently from fluids or solids. Classical continuum theories fail in describing granular matter when the onset of flowing is approached, and his properties, as dilatancy, yield limit, anisotropy and ratcheting. In fact, the behavior at macro-scale is strongly related to smaller-scale field variables and kinetic processes. The goal is to solve this lack with a multiscale approach, coupling discrete and continuum. Getting insights from Discrete Element Method (DEM) simulations a continuum in-homogeneous model will be developed and implemented to describe the macroscopic behavior of the material in terms of homogeneous local properties. A first step is the development of a local constitutive model with anisotropy The model involves only scalar quantities and a new ingredient, the anisotropy. As opposed to isotropic materials, shear strain can cause e.g. dilation and hence compressive stresses, when anisotropy is considered. The local field variables are expressed in terms of material parameters, measured by DEM simulations, leading to a complete calibration of the predictive model.

8.5 Shaping segregation: Continuum modeling of segregation in particulate systems Dense, dry granular avalanches are very efficient at sorting the larger particles towards the free surface of the flow, and finer grains towards the base, through the combined processes of kinetic sieving and squeeze expulsion. Main aim is to develop a unified continuum model of particle segregation, capable of simulating realistic particles and complex system geometries. The model will be able to handle polydisperse flows of irregularly shaped particles with evolving size-distributions. Hence, it will even be possible to predict the behaviour of systems in which the fragmentation/agglomeration of particles occurs. The focus of this research is now on using this model to explain phenomena caused by segregation. These include pattern formation in rotation drums, levee formation in geophysical flows, particle size structure of a flowing finite mass of material in avalanches and axial segregation in long rotating cylinders.

141

The proposed approach involves a powerful combination of particle simulations (S), experimental (E) techniques and continuum modelling (M), producing both theoretical and numerical solutions. The continuum numerical codes will be implemented in the open-source software package hpGEM (http://hpGEM.org), while the particle simulation codes will be implemented in MercuryDPM (http://MercuryDPM.org). These codes will be made available to both academia and industry via new public releases. In 2015 the spin off company MercuryLab (http://www.mercurylab.org) focused on training and consultancy on DEM simulations and MercuryDPM has been launched.

8.6 Discrete particle self-healing material models Using an advanced history dependent contact model for DEM simulations, including elasto-plasticity, viscosity, adhesion, and friction, pressure-sintered tablets are formed from primary particles. These tablets are subjected to unconfined uni-axial compression until and beyond failure. For fast and slow deformation we observe ductile-like and brittle softening, respectively. We propose a model for local self-healing that allows damage to heal during loading such that the material strength of the sample increases and failure/softening is delayed to larger strains. Local healing is achieved by increasing the (attractive) contact adhesion forces for those particles involved in a potentially breaking contact. By healing and sintering, the material strength is enhanced, i.e. the material fails at larger strains and reaches larger maximal stress values, when any of the parameters (a) – (c) is increased. For moderate damage detection sensitivities, the material strength increases with both increasing healing rate and increasing adhesion of the healed contacts. For very large adhesion between the healed contacts an interesting instability with strong (brittle) fluctuations of the healed material’s strength is observed.

8.6.1 Sintering – Modeling of Pressure-, Temperature-, or Time-Dependent Contacts In most realistic situations, where particles come in contact, it can NOT be assumed that the contact properties are independent of pressure, temperature or time. Therefore, this project involves pressure-, temperature-, and time-dependent contact properties and their influence on the macroscopic powder flow behavior. Sintering is chosen as one possible example and starting point, where all these phenomena are relevant. The goal of this project is to model the particles in contact, before the particles lose their identity. For this, temperature- and pressure-dependent contact models have to be developed in parallel to contact-measurements (with Kappl, Mainz). The many-particle simulations will then be adapted to the materials used and experimentally validated (with Tomas, Magdeburg). As the result of the project, a verified numerical model for the sintering process of many particles will become available. This will then be used for the micro-macro transition in order to obtain better theoretical constitutive relations for a macroscopic description based on the contact-mechanics and -physics.

8.7 Micromechanical modeling of asphalt Asphalt is an important road paving material. Besides an acceptable price, durability, surface conditions (like roughening and evenness), age-, weather- and traffic-induced failures and degradation are relevant aspects. In the professional road engineering branch empirical models are used to describe the mechanical behaviour of the material and to address large-scale problems for road distress phenomena like rutting, ravelling, cracking and roughness and phenomena like paving and compaction. The meso-scopic granular nature of asphalt and the chemistry and mechanics of the bitumen layer between the particles is only partly involved in

142

this approach. The discrete particle method is a modern tool that (first of all) allows for arbitrary (self-)organization of the asphalt meso-structure and for rearrangements due to compaction and cyclic loading. This is of utmost importance for asphalt during the construction phase and the usage period, in forecasting the relevant distress phenomena and understand their origin on the grain-, contact-, or molecular scales. The ultimate goal is to derive micro- and meso-based constitutive models that can be applied to model asphalt pavements on the larger (macro) scales. Special focuses are the heat-induced self-healing processes into the mixture and the development of Warm (low temperature) Mixture, by using proper fluidization additives.
