Grain boundary motion analysis in Phase-field theory

The study of materials response to external loads has been always considered among active research interests in scientific community. Recently, by the investigation of materials microstructural changes under deformations and applied loads, significant progresses have been acquired in this field. In this research, by the phase filed modelling of material microstructural behavior, we try to offer a solution for the simulation of grain boundary movement in a bicrystalline aggregate. The validity of this method has been verified by comparing analytic results and computational results. In addition, grain boundary behavior have been investigated when elastic energy difference between two grains increases.
