An unified model for dislocations interacting with complex-shape voids in irradiated metals

The irradiation damage-induced voids can hinder dislocation glide, and thereby change the mechanical properties in the nuclear materials. However, the detailed process of the dislocation interacting with complex-shape void is not revealed well. Here, we study systematically the interaction between an edge dislocation and a polygonal void with different initial geometries in the irradiated metals by dislocation dynamics simulations, in terms of...
