c. Research
c.1 Research programs underway
1. Crystal Plasticity modeling: Our group specializes in crystal plasticity modeling for
modeling metallic material response at the mesoscopic scale. Most structural metallic
materials are composed of aggregates of single crystals. Plastic flow in a single crystal is
anisotropic, and cannot be modeled using simple yield models. Instead, a complex
material law is used, which models unit mechanisms such as slip and twin activity. Using
this model, we simulate the crystallographic rotations of individual grains in a polycrystal
to predict texturing, and we predict stress-strain response at the structural scale. The
PRISMS DoE software center grant enabled development and distribution of an open
source crystal plasticity finite element code to the broader research community. The code
is publically available at https://github.com/prisms-center/plasticity
2. Multi-scale materials design: This project focuses on computational multi-scale
design/optimization approaches for tailoring engineering properties of metallic materials.
Of particular interest is the use of controlled deformation processes to tailor evolution of
microstructural features such as crystallographic texture. The design problem involves
prediction of process conditions (forging velocity, preform shape etc.) that lead to a
desired microstructure distribution in the material. Here, micro-scale evolution is solved
with crystal plasticity at the integration points of a finite element large deformation
simulation. The inverse problem is by far (at least on the basis of computational
complexity alone, with billion microstructural degrees of freedom) a challenging inverse
problem. Highlight of our approach is a multiscale continuum sensitivity analysis scheme
for rapidly computing the sensitivity of microstructural features to change in process
parameters. Using this approach, we have demonstrated design of tailored 'high strength'
(eg. turbine disk) or 'minimal magnetic hysteresis loss' (eg. transformer cores) structures.
Our research with National Science Foundation supported theoretical and computational
investigation of new thermo-mechanical processes for manufacturing low-cost
polycrystalline iron-gallium alloy (Galfenol) with properties comparable to expensive
single crystals. Our collaboration with UTRC is on development of the method for
modeling processing of third generation aluminum lithium alloys for fan blades.
3. Markov random fields for microstructure synthesis: Currently available methods for
microstructure synthesis such as geometry based (eg. Voronoi models), physically based
(eg. Phase field models) or feature-based (eg. Simulated annealing) methods run into
various difficulties when modeling complexities of microstructures such as
nonequilibrium grain structures, non-convex grains, twins, second phases and cell
structures that naturally arise from material processing. These features play an important
role in the properties and performance of modern aerospace alloys. Further, stochasticity
of microstructures lead to location-specific variability in material properties, and a single
instance of a microstructure does not adequately model the property distribution in a
component. In this project, we delve into a mathematical model that is expected to
provide a robust alternative for microstructure synthesis: Markov random fields (MRFs).
We are developing theory and software for building three dimensional (3D)
microstructural maps of engineering components through Markovian inference from two
dimensional (2D) measurements.
4. Reduced order descriptors for microstructure modeling: As a part of the 'basic research
challenge'(BRC) team selected by the office of naval research, we investigated
alternatives to computationally expensive crystal plasticity finite element modeling
(CPFE) of polycrystalline microstructures for multiscale modeling of deformation
processes. Recently, we have developed the general theory behind physics-based
modeling and scale-linking of three reduced order descriptors with increasing levels of
microstructural information: (i) Orientation distribution function (ODF) which contains
crystallographic texture, (ii) Grain size orientation distribution function (GSODF) that
contains texture as well as grain size/shape information and (iii) Conditional orientation
correlation function (COCF) and nearest neighbor orientation correlation function
(NNOCF) that contains texture as well as crystal neighborhood information. The
common theme in our approach is the use of Lagrangian finite element analysis to
directly evolve the ‘descriptor’ (rather than the actual microstructure) during
deformation. We have shown that the approach is significantly faster than CPFE and will
result in orders of magnitude speed up for microstructure sensitive design of advanced
titanium alloys used in aircraft and naval structures.
5. Multi-scale modeling of composites in extreme environments:
i. Ceramic matrix composites: We have developed a multi-scale (macro-micro)
methodology to study degradation of ceramic matrix fiber reinforced composites
in high temperature oxidizing environments. The method integrates multiple
physics associated with microstructure degradation including thermal transport,
chemical reaction kinetics, thermo-mechanical deformation, matrix damage
accumulation, diffusion of oxygen/oxides and carbon fiber surface recession at
the microstructural level. The macro-to-micro coupled model has the ability to
quantitatively capture oxidative mass loss and mechanical behavior at high
temperatures as reported in published experiments (Past support from NASA).
ii. Energetic composites: With support from DTRA, the multiscale approach was
extended to include high rate (detonation wave) physics for a HMX/polymer
composite system. We include equations of state for every component, chemical
reaction rates, heat generation and have developed mixture rules to model
solidgas mixing. The method has been implemented using Taylor Galerkin
approach with flux limiter schemes for modeling sharp shock and detonation
waves.
6. Atomistic modeling of epoxy resins and nanocomposites: We specialize in molecular
dynamics simulations of polymer nanocomposites. These simulations are used to
computationally determine the thermomechanical properties of cured thermoset or
thermoplastic resins reinforced with pristine or covalently functionalized nanostructures.
The thermoset structure building is performed using the ‘dendrimer’ growth approach
that leads to equilibrated atomistic structures with properties that closely reproduce
measurable engineering properties such as stiffness, thermal expansion and conductivity.
By adding nanostructures with different chemical functionalizations, these techniques
allow design of polymers even before they are synthesized. Micromechanical theories are
used to obtain the properties of larger-scale isotropic system of oriented nanotubes in
epoxy. Theoretical models show substantial improvements of functionalized
nanocomposites over plain epoxy in terms of higher stiffness (200% increase) and lower
thermal expansion (32% reduction).

c.4 New research directions
1. Uncertainty quantification for materials science: Although there has been extensive
work on multiscale modeling of materials, an understanding of the effect of intrinsic
microstructure uncertainties on macro-scale engineering properties is still lacking. In
this work, we aim to bridge this gap by developing stochastic analysis tools
(specifically, analytical methods for uncertainty propagation). We are also working
on an efficient multi-scale stochastic sensitivity analysis technique in the context of
managing uncertainties in materials-by-design approaches. We have developed
uncertainty quantification and design techniques to optimize these reduced order
descriptors to obtain microstructures with desired property distributions.
2. Metallic Fracture and Fatigue: Multi-scale analysis is used for computation of failure
of metals under static/ cyclic loads and external environment. Computational themes
include crystal plasticity, dislocation dynamics, molecular dynamics and density
functional theory. In an ONR program, we developed models for environmentally
assisted failure based on cohesive energies computed from DFT calculations. We
have used molecular dynamics to compute failure along grain boundaries and its
effect of intergranular decohesion and failure. We couple crystal plasticity finite
element method with variational multiscale method for modeling arbitrary crack
paths (both transgranular and intergranular). In the DoE software center, we employ
dislocation dynamics simulations to inform cyclic crystal plasticity models for
simulation of low cycle fatigue failure.
3. Nonlocal theories and peridynamics: Unlike local theories, non-local elasticity
theories take into account the multi-atom interactions that determine stress state at the
nano-scale. Non-local theories may overcome several issues associated with local
models, for example, local elasticity predicts infinite stresses at a crack tip and does
not predict size effect in elastic properties at the nanoscale. In collaboration with Dr.
Anthony M. Waas, we worked on methods to directly build accurate non-local
models of Carbon nanotubes from dispersion curves obtained from molecular
simulations. A collaborative paper was published discussing the physical properties
of the non-local kernel. The project was supported by Boeing Company. Recent work
has continued development of non-local models based on the peridynamic
formulation. Peridynamics is a non-local formulation of continuum mechanics that is
promising for modeling fracture and gradient effects. We developed the first
implementation of crystal plasticity within state-based peridynamics theory and have
developed new algorithms based on both explicit and implicit methods for integration
of peridynamic equations of motion.
4. Materials informatics: Data-mining techniques are eminently suitable for materials
design since optimal microstructures can be selected based on available information
from a large database relating processes, properties, and microstructures. A
hierarchical X-means classifier and support vector machines algorithm have been
developed to enable automated identification of such relationships by mining over a
database of microstructural signatures. These methods were employed for multiscale
design of Galfenol and Titanium alloys in an AFOSR funded MURI in collaboration
with Northwestern University.

c.7 Technology Transfer and Entrepreneurship
My contributions to technology transfer have been through direct contact with
government research laboratories and industry. I have interacted with NASA, NRL
and AFRL to convey my research results and have provided them with the research
codes and articles. One of my research works on microstructure data mining was one
of the two citations in the US Army’s Small Business Technology Transfer (STTR)
Program solicitation number A06-T009 titled “Performance maps for Low-Cost
Titanium Armor”. I have developed extensive simulation codes for modeling epoxy
matrix materials using molecular dynamics for use by Boeing R&D as a part of a
current research grant. During my sabbatical in winter 2015, I collaborated on a SBIR
contract with Scientific Forming Technologies Corporation (SFTC) for integrating
our microstructural descriptor based techniques in their proprietary forming
simulation software (DEFORM) that is being used by dozens of industries. I worked
with Boeing and UTRC as a part of the LIFT center activities at UM developing a
crystal plasticity model for dynamic recrystallization of Aluminum and Titanium
alloys.
