Crystal Plasticity Simulation of Microstructured Materials

Abstract : Bridging from the knowledge about potential deformation
mechanisms at the scale of individual crystals to predictive capabilities
for engineered materials (or structures) frequently requires consideration
of the mechanical response of the microstructure. I will start by briefly
explaining the fundamentals, advantages, and shortcomings of an efficient
methodology to solve mechanical equilibrium in (quasi-) periodic
structures at high spatial resolution. This so-called spectral method is
then contrasted with the more commonly utilized finite element method. In
a second part, recent application examples pertaining to micromechanical
questions will be presented. Among those are the response of
(two-dimensional) monocrystalline stochastic honeycomb structures, the
influence of subsurface grains on surface mechanics, and the relevance of
smaller grains for the overall polycrystal mechanics.

Associate Professor Philip Eisenlohr studied materials science and
engineering at Universität Erlangen–Nürnberg, Germany, and
received his PhD in 2004. Dr. Eisenlohr was research group leader at the
Max-Planck-Institut für Eisenforschung GmbH, Düsseldorf,
Germany, before joining the Michigan State University Chemical Engineering
and Materials Science department in 2013. His research focus is on
mechanics of micro/nano-structured materials with an interest in basic
science of plastic deformation mechanism in metals combined with the
advancement of associated simulation methodologies. His major research
target is the acceleration of materials design through Integrated
Computational Materials Engineering (ICME) based on physically accurate
descriptions of governing mechanisms. Investigated material classes
include high-strength (twinning-induced plasticity) steels, titanium
alloys, and tin-based solders.
