Abstract: This talk will focus on the simulation and analysis
of the effects grain growth has on the properties of polycrystalline
materials. Several kinetic models have been developed in recent years that can
predict coarsening rates and accurately describe evolution of important grain
boundary distributions. This talk will focus on the progress made in combining
these novel mesoscopic level descriptions with macroscopic microstructure
analysis tools such as OOF2. In particular, it will discuss the strategy for
quantifying the rates of degradation experienced by the microstructure during
coarsening and quantify the impact texture and other initial grain boundary
distributions have on the local stress/strain development and other materials
properties. Some discussion of the novel simulation and numerical modeling
techniques used in this analysis will also be provided.
