DISLOCATION DYNAMICS AND BRITTLE-TO-DUCTILE TRANSITIONS
The validity of different types of models for crack-dislocation interactions and their effect on fracture is discussed. The brittle-to-ductile transition (BDT) in precracked silicon and sapphire can be described by a two-stage dynamic model based on dislocation motion to and around the crack tip. In...
