Dynamic Relaxation and New Periodic Symmetry Technique for Simulating Interactions Between Dislocations

Studies of the interaction between two edge dislocations have been carried out by coupled Dynamic Relaxation (DR) technique, the Embedded Atom method (EAM) potential function and a newly developed periodic symmetry method. The effects of boundary conditions and external tractions are examined for the case of edge dislocations with the same or opposite Burgers vectors gliding on physically the same planes, and for dislocations with opposite …
