Abstract:

Modeling the mesoscale behavior of irradiated materials is an essential aspect of developing a computationally predictive, experimentally validated, multiscale, understanding of the thermo-mechanical behavior of nuclear fuel. Phase field models provide a flexible representation of time-dependent heterogeneous materials. We explain how differential variational inequalities (DVIs) naturally arise in phase field models, and we discuss recent work in developing advanced numerical techniques and scalable software for DVIs as applied to large-scale, heterogeneous materials problems.
