Dislocation dynamics (DD) is a modeling approach for the study of crystal plasticity wherein individual dislocation lines are discretized and their motion in the crystal is simulated. This …
Dislocation motion and interactions are the main processes controlling the plasticity of crystalline solids. When a dislocation glides by an elementary atomic step in a crystal, it …
Dislocation dynamics (DD), a discrete dynamic simulation method in which dislocations are the fundamental entities, is a powerful tool for investigation of plasticity, deformation and …
