PHASE FIELD MODELING OF NORMAL AND STRESSED GRAIN GROWTH: THE EFFECT OF RVE SIZE AND MICROSCOPIC BOUNDARY CONDITIONS

Multiscale modeling of microstructure evolution in polycrystalline metals is involved with the concept of a representative volume element (RVE) that represents a material point under consideration. Phase field modeling of microstructure evolution due to grain boundary migration is commonly performed with a rectangular RVE in 2D or a cubic RVE in 3D. In this paper, phase field simulations are used to investigate the RVE size and boundary...
