Short-range dislocation interactions

Short-range dislocation interactions are inherently atomistic and can only be investigated at present by means of atomistic simulations. Large-scale m olecular-dynamics (MD) simulations can provide a great deal of quantitative information about the generation, motion, and interaction of dislocations, which are processes not easily accessible at present to experiments. In th is paper, we will show the necessity of atomistic simulations in investigat ing short-range dislocation interactions by analyzing junction formation an d jog formation in the: process of dislocation intersection.
