Abstract

Two distinct approaches are commonly invoked to explain the brittle to ductile transition of a material in the presence of a crack. In one approach, dislocation mobility plays the key role. In the other approach, the competition between crack tip dislocation nucleation and cleavage failure plays the key role. The two approaches are reconciled in the present study.
