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.
