1 Introduction 11 Background The use of the finite element method (FEM) to simulate structural responses to extreme loadings is a well established practise in design of buildings and structures today Modern FEM software codes in structural engineering are verified and validated against a vast number of experimental results ranging from minute testing of engineering materials for the verification of constitutive models via high precision testing of structural elements for investigating local failure modes to full scale tests of real structures to verify the global response under realistic loading scenarios Full scale blast tests of real structures are rare because of their size complexity and above all the costs required for their execution Hence high precision tests of full scale structures are always met with great interest and enthusiasm in the scientific society since such tests represent an excellent opportunity to check a complex FEM-model with all its assumptions against a verified outcome The present report presents the outcome of a numerical study of a full scale blast test of an unprotected 20 ft standard ISO steel container The blast test was part of a comprehensive research programme executed by the SIMLab group at the Department of Structural Engineering The Norwegian University of Science and Technology (NTNU) in Trondheim Norway The tests aimed at verifying the behaviour of standard 20 ft ISO containers used as shelters in international operations such as peace-keeping operations rescue and reconstruction operations in international conflict areas 1 The blast tests were carried out in the Large Blast Simulator (LBS) at the Bundeswehr Technical Center for Protective and Special Technologies (WTD 52) in Oberjettenberg Germany 2

12 Collaboration framework The present study was carried out under the Physical Vulnerability Assessment of Critical Structures (PVACS) action of the JRC ELSA unit The numerical simulations were performed by use of the explicit finite element (FE) code EUROPLEXUS 3 while the specific detailing and build-up of the FE-model of the container was carried out by use of the general purpose finite element code Cast3M 4 Access to the detailed test results from the blast tests and the experimental set-up has been granted to the JRC under a collaboration agreement titled Structural Safety and Security between the JRC and the Department of Structural Engineering NTNU in 2007 5 Valuable additional information related to the test site in Germany has been provided by direct input from the WTD 52 in Germany

13 Organisation of the report The numerical simulations in this study include two phases In the first phase the container was subjected to an applied pressure-time loading on the longitudinal wall of the container that was facing the explosive charge in the tunnel The applied pressure-time loading was derived by a simple pressure-time routine in EUROPLEXUS called AIRB 6 which calculates the pressure acting on an object

based on the explosive charge and the stand-of distance between the explosive charge and the object In the second phase the container was loaded with the set of pressure-time curves actually recorded during the experiment and reported in 1 The experimental set up is briefly presented in Chapter 2 together with some of the main results from the blast test Due to ownership issues and restricted information related to the NTNU project the interested reader is referred to reports issued from NTNU eg 6 7 and 8 for further details Chapter 3 presents the detailed build-up of the FE model of the container while the load conditions the main results from the simulations and comparison between the test results and the numerical findings are presented in Chapter 4 Discussions and conclusions are presented in Chapter 5 followed by a list of relevant publications in Chapter 6

2 Blast test of a 20 ft ISO container 21 General A 20 ft standard ISO steel container was subjected to a blast test in the Large Blast Simulator (LBS) at WTD 52 in Germany The blast simulator is basically a dead-end tunnel of approximately 100 m length and a rectangular-semicircular 1284 m wide cross-section with a height of about 700 m The tunnel is slightly inclined towards the opening with a slope of around 4 See the sketch in figure 1 below The tunnel is equipped with a battery of 100 high pressure steel vessels located at the dead-end of the tunnel each of them with the capacity of delivering 384 litres of compressed air up to 200 bars When the compressed air in the pressure vessels is simultaneously released by explosive devices cutting of steel diaphragms at the end of each vessel the air expands and forms a plane blast wave travelling down towards the opening of the tunnel By manipulating the pressure level in the vessels as well as the release time of the diaphragms this blast facility can simulate pressure waves with side-on pressure in the range of 5 to 100 kPa and with durations in the order of seconds The tunnel is further equipped with baffle sections three internal walls with rectangular openings gradually reduced down to a final rectangular opening of 6x5 m forcing an improved plane pressure wave to arrive at the test specimen location 40-100 m down the tunnel Figure 1 A schematic view of the Large Blast Simulator (LBS) at Bundeswehr

22 Test set-up A standard 20ft ISO steel container was positioned at the mouth of the tunnel 95 m away from the pressured steel vessels delivering the pressure wave A series of blasts against an instrumented rigid concrete wall of 3x3 m were conducted in order to calibrate the pressure-time behaviour of the blast to a given design blast load representing 4000 kg TNT at a standoff distance of 120 m 1 The container was mounted with one of the longitudinal walls facing the blast front and fixed to the ground by a total of 7 clamps two on each short wall sides and 3 along the rear longitudinal wall These claps were made of angular steel brackets welded to the bottom frame of the container and bolted to the concrete floor of the blast tunnel The container was fully instrumented by means of a set of pressure gauges for recording the pressure at various locations of the container during the blast A laser gauge was set up to measure deflections and 3 high-speed cameras were used for visualization of the blast load response Though some of the instruments failed during the test a fairly comprehensive and consistent set of data was recorded by the data acquisition system For the unprotected container a total of 5 pressure gauges were mounted on the container at the mid-point of the longitudinal front wall and the longitudinal rear wall at the mid-point of the short wall on the roof and finally one gauge was mounted on the inside of the doors of the container A laser gauge registered the deflections of the mid-point of the longitudinal front wall The locations of the gauges are shown in figure 2 Additional details about the test set-up can be found in 1

23 Test results A complete discussion of the test results for the blast load on the container is given in 1 Here only the main findings will be listed for the purpose of the comparison between the experimental results and the present numerical simulations of the container subjected to the same blast load as in the experiments Unfortunately the pressure gauges mounted on the longitudinal front wall and the longitudinal rear wall failed during the test However a later test performed on a similar container but with a protective wall mounted in front of the container facing the blast source gave a complete set of pressure-time readings throughout The authors of 1 opined that those results would suffice as a substitute for the lacking readings from the blast test of the unprotected container That position has been adopted also in the present study The pressure-time curves registered during the test are shown in figure 3 below It shall be noted that these are the overpressure values that is relative to the atmospheric pressure Hence the zero value in the pressure time curves represents the atmospheric pressure level (1 atm asymp 1 bar = 100 kPa) The peak value of the pressure recorded for the roof reached 38 kPa after approximately 380 ms and then gradually turned into negative pressure levels around 410 ms with peak values from -15 to - 28 kPa in the time interval of 440 - 500 ms See figure 3 top graph This rather pronounced peak in the negative pressure-time evolution was possibly due to reflection from the roof of the tunnel The registered pressure on the longitudinal front wall see figure 3 bottom graph exhibited a somewhat similar build-up of the pressure as for the roof The peak pressure level reached about 35 kPa at approximately 375 ms and only minor negative pressure levels around -5 kPa were registered in the final part of the pressure-time curves A significant internal pressure did build up in the container during the blast reaching a peak value of 22 kPa at 395 ms then to gradually turn into a negative pressure phase at 440 ms with a peak value in the order of -5 kPa around 450 ms It is interesting to compare the pressure levels on the container from both the outside and inside pressure gauges with the time level of the outward deflection of the roof as seen in figure 4 The deformation of the container was registered on the mid-point of the longitudinal front wall by use of a laser gauge The total deflection went beyond the working area of the laser gauge hence the maximum deflection of the wall was not properly registered However 1 reported that based upon post-assessment of the container the total plastic and elastic deflection of the mid-point was estimated to reach ndash 485 mm (inward deflection) The detailed deflection-time curve is given in figure 4 1 It was further reported in 1 that the top beam of the container had a permanent downward deformation of about 110 mm and a permanent inward displacement of 60 mm The roof exhibited an outward plastic deflection of about 300 mm No fracture of the container was observed

3 The finite element model of the container 31 General The finite element (FE) models of the container were established by use of the general purpose finite element software Cast3M 4 Due to the rather complicated geometry of the various structural components of the container with corrugated wall panels and roof elements open-shaped columns and beams as well as the assemblage of the structural components the geometry of the finite element (FE) model of the container was established using a special algorithm developed at JRC ELSA for handling node numbering and mesh resolution issues originally developed for masonry structures 9 The algorithm allows for the meshing of structures made of blocks or separate regions connected together by joint interfaces By starting from the definition of the corner nodes of a given region the algorithm is able to produce the mesh of each region in such a way that the faces that are in contact are topologically identical This approach allows also an easy generation of joint elements if those are to be included in the analyses eg welds However for the present FE-models of the container complete material connections between the various structural elements were assumed hence no joint elements were defined The generation of compatible regions is based on an algorithm that inspects each region and if a master node of another region geometrically lies on this segment the node is duplicated and added to the description of the current region As a result the master nodes lying on the contact lines between two regions are two-by-two placed at the same location Hence the meshing strategy allows automatic meshing of the regions in such a way that the contour lines of two regions in contact are discretized in a similar way The principle is illustrated in figure 5 below while a complete description of this approach both for 2D and 3D examples is given in 9 Figure 5 Additional master nodes in non-compatible regions 9

This meshing method was very efficient and useful for merging together in a topologically consistent way the rather complicated intersections between the corrugated wall panels and the flanges of the bottom and top beams with their U-shaped cross-sections As illustrated in figure 7 these intersections would have been very difficult to discretize by a more traditional method Together with the objected oriented nature of Cast3M which allows for duplicating mirroring and translating geometrical objects the FE-model of the container could be defined in a consistent way by an input file that when executed by use of Cast3M generated a FE-model of the container that was later imported into Europlexus for the final numerical blast load simulations A highly useful outcome from this approach to the build-up of the FE-model of the container was that in order to change the mesh resolution of the FE-model only the density parameter of the meshes of the longitudinal walls had to be changed in the input file This approach proved also useful for the mesh size dependency runs carried out in the present study in that it saved the operator much tedious work and the gain in time was significant The complete input file for the FE-model of the container is given in Appendix A Figure 6 Standard 20 ft ISO container 1

32 FE-model The FE-models of the container were detailed based upon drawings and information received from SIMLab 1 The global dimensions of the 20 ft ISO container were 2438x2591x6058 mm and the container was made up by a frame structure of cold formed channel-shaped or hollow beams and the walls roof and doors were made of corrugated steel panels of various shapes The base structure was constructed of two longitudinal beams of 48x158x30 mm 45 mm thick welded together with a front beam of 40x166x40 mm and 40 mm thick and a rear beam with the cross-sectional dimensions 40x150x50x70 and a thickness of 40 mm 16 equally spaced cross-over beams with dimensions 45x122x45 40 mm thick were welded between the longitudinal side beams of the base frame The floor of the container was made of plywood plates fixed to the base structure by self-tapping screws A somewhat similar layout shaped up the top frame however hollow squared beams of 60x60 mm 30 mm thickness were used there for the longitudinal beams and the front beam while a channel shaped beam of 132x113x132 mm with a thickness of 40 mm was used for the rear beam The top frame was supported by four corner columns welded to the top and bottom frames The front corner columns had multi-faceted cross sections of 50x50x154x170x50x50 mm with a thickness of 60 mm while the rear corner columns were made up of two profiles a 50x40x166x50 mm 60 thick profile and a 50x113x50 100 mm thick profile respectively joined together by continuous welds Corrugated steel panels of 20 mm thickness welded continuously to the frame structures were used for the side walls the front wall and the roof respectively The shape of the corrugated steel panels varied a bit as can be seen from the detailed drawing in figure 9 The rear part of the container was made up by two doors hinged to the rear corner columns and closed to the rear frame of the container with 4 vertical bar locks Each door consisted of a closed steel frame of rectangular hollow steel beams with the dimensions 100x50 mm and 32 mm thick framing a 20 mm thick corrugated steel panel fixed to the door frame by continuous welds See 1 for further details The main structural parts of the container such as the corrugated panels the corner columns and most of the beams were made of anti-corrosive steel named Corten A SPA-H B480 or equivalent with a yield stress around 345 MPa and a tensile strength of about 520 MPa Though some minor parts of the container were made of steel with a somewhat lower yield stress and tensile strength limit the above values have been used for all parts of the container for the calculations carried out in the present study

The constitutive model applied for the Corten steel was a Von Mises material model with elasto-plastic behaviour implemented via a radial return algorithm Only isotropic hardening was treated and neither temperature nor strain rate dependency were introduced in the calculations The key parameters for the constitutive law used in the calculations were the yield stress 0 2 345 MPaσ = the tensile strength limit

520failure MPaσ = density 37850 kg mρ = Youngrsquos modulus 210000E MPa= and the Poissonrsquos ratio 0 3υ = The container geometry was discretized by use of 4-node shell elements (Batoz) with 4 integration points in the plane and 5 integration points over the thickness for plasticity combined with 3-node shell elements (Discrete Kirchhoff Triangle) based on the thick shell element theory (Mindlin) The various structural elements of the FE-model of the container are presented in figure 7 above identifying in a simplistic form the cross-sectional dimensions and thicknesses of the various elements

4 Numerical simulations 41 General The numerical simulations were grouped in 2 different sets of calculations The first initial set of calculations were based on imposed pressure-time curves on only the longitudinal front side of the container derived from the findings in the tests 1 These pressure-time curves had been calibrated against rigid wall blasts in order to aim towards prescribed design loads similar to the design pressure loads calculated by the ConWep 10 procedures 1 Based on the blast tests towards a rigid wall 1 the explosive charge and the stand-off distance were set to 4000 kg and 120 m respectively These initial set of calculations were used to study the mesh size dependency of the numerical models of the container in that two different mesh resolutions were compared against each other The second set of calculations was a more elaborate study of the behaviour of the numerical model of the container In particular a more complete pressure-time loading of the container was performed including also the pressure history recorded for the roof of the container The pressure-time histories were taken directly from the registered values in the blast tests 1 In the following these two sets of calculations are discussed in more detail 42 Initial calculations Two different mesh resolutions were used in these initial calculations one with a typical mesh size of 100 mm relative to the global dimensions of the container and one with a typical mesh size of 50 mm respectively This yielded a total number of 16332 finite elements for the coarser meshed model named cont250 in the following and a total of 43034 finite elements for the finer meshed model named cont500 Some data for the models are listed in Table 1 The imposed pressure-time curve on the longitudinal front wall of the container was calculated automatically by use of the AIRB-routine in EUROPLEXUS code The AIRB-routine was developed by M Larcher 11 and the routine is based on the same underlying equations as for the ConWep 10 formulae and gives similar pressure-time curves for identical inputs The AIRB-routine calculates an imposed pressure-time sequence on a given object in this case the longitudinal front wall towards the source of the explosion The input parameters of the routine are the explosive charge in kilograms the scaled distance between the explosive charge and the object (the steel container in this case) and the nature of the explosion that is whether it takes place on the ground above the ground etc Further details can be found in 11 The AIRB-routine allows to load the structures without having to model the fluid domain It does not take into account multiple wave reflections on structural walls but optionally allows to take into account in a very simplified way the first wave reflection at a wall It is clear that for the steel container tested in the blast tunnel in

2 this approach only serves as a rough first assessment of the numerical model of the container The following input has been used in the calculations of the blast wave Explosive charge in kilograms = 4000 kg Stand-off distance from object = 120 m Nature of the explosion = hemispherical charge no reflective blast considered The pressure-time curve generated by the AIRB-routine and applied as pressure-time loading of the longitudinal front wall of the steel container is shown in figure 8 below Figure 8 Pressure versus time function applied on the container The two FE-models cont250 and cont500 respectively were subjected to the above pressure-time function applied to the longitudinal front wall of the container The number of FE-elements the total cpu time and the duration of the pressure-time loading for the two models are summarised in Table 1 below

The overall behaviours of the two models were rather equal the coarser meshed model cont250 acting somewhat stiffer than the model cont500 with the finer mesh as seen in figure 9 Both models exhibited similar stress levels during the loading as

can be seen in the von Mises stress levels versus time plots in figure 10 below however the response of the cont250 model was clearly stiffer than that of the cont500 model as illustrated in the x-displacement versus time plots in figure 11 Both plots relate to nodes at the mid-level of the longitudinal front wall of the container model Detailed plots of the deformed configurations after loading for the models cont250 and cont500 are compared in figure 12 below From these preliminary calculations it was decided to continue the simulations with the finer mesh resolution although the differences between the two models were quite small

models respectively 43 Refined calculations The initial calculations were based on a simplified pressure-time function for the explosive impact on the container It is clear that such an approach may well fall short in describing the real behaviour of the rather complex loading situation the container underwent in the blast test tunnel in Germany In particular the container in the blast tunnel test experienced a pressure loading quite different from that of an imposed pressure-time loading on the longitudinal wall only As can be seen from the recorded pressure-time development in figure 3 the container was engulfed by pressure waves as the initial pressure wave travelled through the blast tunnel Both pressure as well as suction took place on all sides of the container and internal pressure built up during the deformation and successive collapse of the container In particular the roof of the container experienced a significant increased suction loading after the initial pressure wave hit the roof indicating a possible reflection from the blast tunnel roof 1 A more realistic representation of the pressure loading of the container would hence yield better results compared to the test results from 1 It was therefore decided to

apply two pressure-time curves on the container one on the longitudinal wall and one on the roof no sides no back These pressure-time loadings were derived directly from the recorded results during the tests in the blast tunnel in Germany 1 and 2 The resulting pressure-time curves for the longitudinal wall and the roof were derived from the recordings in figure 3 in that the net resulting pressure of the wall was calculated as the external pressure minus the internal pressure over the duration of the test and the roof pressure as the external pressure registered on the roof minus the internal pressure registered in the container The two simplified pressure-time curves applied to the container in these somewhat refined calculations are shown in figure 13 The refined calculations were run with the same mesh resolution as in the cont500 FE-model The model was named cont1000 to distinguish it from the models used in the initial calculations The total number of finite elements the total cpu time and the duration of the pressure-time loading are in Table 2 below Note that the final duration is twice that used for the initial calculations Further the imposed pressure-time loading was applied directly to the structure and not calculated by the AIRB function used in the calculations of the cont250 and cont500 FE-models respectively

Cont1000 43034 108842 s 0200 s The deformed shape of the container is presented in figure 14 below for 8 various time steps of the applied pressure-time histories A fairly good correlation between the global deformation pattern of the numerical model cont1000 and the real behaviour of the container during the blast tests can be observed in figure 16 where the permanent deformed configuration of the numerical container model after loading is compared with the final image of the container during the explosion test in the WTD 52 blast tunnel Both the distinct yield line failure pattern of the longitudinal front wall as well as the outward deflection of the container roof were well captured by the numerical FE-model of the container It shall be stressed that this is to be expected to some extent in that the applied pressure-time history is the same as registered during the test However it is an important result in itself in particular from an engineering design point of view that the numerical model if sufficiently discretized in terms of mesh resolution and precisely reproduced in terms of geometry and material parameters is able to grasp the global behaviour of the rather geometrically complex container as precisely as seen in figure 14 and figure 15

The mid-wall deflection and stress history during the imposed pressure-time loading were also fairly close to those observed during the tests A maximum stress level in the mid-point of the wall arrived at approximately 360 MPa pushing the material into permanent deformations The total displacement of the mid-point of the longitudinal front wall reached around 270 mm while the remaining permanent displacement after unloading was about 220 mm For the roof structure the maximum stress level reached 360 MPa (mid-point of the roof) during the inward deflection of the roof then up to 380 MPa when the roof bent outwards snapping back due to the negative pressure pulse hitting the roof later in the pressure-time loading history Hence also the roof exhibited large permanent deformations as seen in the above figures The maximum displacement of the roof reached -500 mm during the inward deflection and a displacement of 500 mm during the outward deflection in the final phase of the loading The permanent outward deflection of the roof was about 380 mm The top wall-roof beam experienced a maximum inward displacement (x-direction) of 180 mm and a final permanent displacement of 100 mm The displacement in the vertical direction (z-direction) arrived at about ndash 50 mm and a permanent downward deformation in the order of -25 mm worth recalling test values Stress-time curves for the longitudinal front wall and the roof are shown in figure 16 below while the maximum displacement-time curves for the same points are shown in figure 17 below Figure 16 Deformed container model The dots represent the locations of the

The only direct displacement measurements carried out during the blast test were at the mid-point of the longitudinal front wall presented in figure 4 above 1 Direct comparison between these recordings and the numerical results for the cont1000 model is given in figure 20 below Although the numerical simulations failed to some extent in replicating the maximum displacement value reported in 1 the overall displacements for the cont1000 model showed good accordance with the experimental results

5 Discussions and conclusions The current numerical calculations results presented above for the 20 ft steel container subjected to blast loadings showed relatively good agreement with the reported results from the blast tunnel tests executed by the SIMLab team 1 The two numerical models cont250 and cont500 that were subjected to a simplified pressure-time loading fell somewhat short in describing the global failure mode of the container This was mainly due to the fact that only the longitudinal front wall of the container was loaded in the numerical calculations for cont250 and cont500 while the container during the blast tests was engulfed by a rather complex pressure wave loading which included a significant negative pressure on the roof of the container during the final part of the blast Hence the simplified numerical calculations did not include the collapse of the roof structure and consequently the significant weakening of the support of the longitudinal front wall due to the deflection of the roof However both the cont250 and cont500 calculations were able to replicate the failure mode and failure level of the longitudinal front wall with fair accuracy Both the distinct yield line pattern of the longitudinal front wall as well as the permanent plastic deformations seen in the blast tests were clearly identified in the numerical calculations The displacement of the longitudinal front wall was less for the cont250 model than for the cont500 model due to a stiffer overall response caused by the coarser finite element mesh resolution used for the former model The numerical calculations for the cont1000 model differed from the others by the applied pressure-time loading The same finite element mesh resolution as for the cont500 model was used but the applied pressure-time loading was derived directly from the recorded pressure values from the blast test performed by SIMLab 1 The longitudinal front wall and the roof were loaded by two separate pressure-time loadings over a duration of 0200 s The cont1000 calculations replicated the global failure mode of the container very well The yield failure pattern of the longitudinal front wall was in close agreement with the observed failure of the container in the blast test and the inward deflection of the roof followed by an outward deflection caused by the negative pressure in the final phase of the blast were precisely captured by the cont1000 model Although the final permanent deformations of the container generally were lower than those observed during the blast test of the container the overall behaviour of the cont1000 model was generally in close agreement with the observations from the blast test The maximum deformations of selected regions of the container are compared in Table3 The permanent deformations of the same regions of the container are listed in Table 4 below The results from the current study demonstrate that a sufficiently discretized finite element model with well described material parameters and realistic representation of the applied blast loadings can replicate the global behaviour of a structure to a very high degree Both local behaviour of critical regions in terms of stress-levels and deformations were well captured by the numerical models and the overall global failure modes were closely reproduced when compared to the experimental blast test results

European Commission Joint Research Centre ndash Institute for the Protection and Security of the Citizen Title Simulation of a Standard ISO Steel Container Subjected to Blast Loading Author(s) Torbjoern Dyngeland 2010 ndash 45 pp ndash 210 x 297 cm Abstract The report presents the outcome of a numerical study of a full scale blast test of an unprotected 20 ft standard ISO steel container performed in a project of the Department of Structural Engineering NTNU Norway In the present study numerical simulations were performed by use of the explicit finite element (FE) code EUROPLEXUS while the specific detailing and build-up of the FE-model of the container was carried out by use of the general purpose finite element code Cast3M The container was modelled using a Von Mises material model with parameters for standard Corten steel quality Only isotropic hardening was treated and neither temperature nor strain rate dependency were introduced in the calculations Calculations based on an imposed pressure-time loading history (corresponding to 4000 kg TNT and a stand-off distance of 120 m) on the longitudinal front side of the container were performed The mesh size dependency of the numerical models was investigated The second set of calculations was a more elaborate study of the behaviour of the numerical model of the container where a more complete pressure-time loading was applied including also the pressure history for the roof of the container These pressure-time histories were taken directly from the registered values in the blast tests The results from the current study demonstrate that a sufficiently discretized finite element model with well described material parameters and realistic representation of the applied blast loadings can replicate the global behaviour of a structure to a very high degree Both local behaviour of critical regions in terms of stress-levels and deformations were well captured by the numerical models and the overall global failure modes were closely reproduced when compared to the experimental blast test results
