Abstract

Modeling nuclear radiation damage necessarily involves multiple scales in both time and space, where molecular-level models have drastically different assumptions and phenomena than continuumlevel models. In this thesis, we propose a novel approach to explicitly coupling these multiple scales of the microstructure damage of radiation in materials. Our proposed stochastic process is a statistical upscaling from physical first principals that explicitly couples the micro, meso, and macro scales of materials under irradiation.
