..., but also on the direction of the crack propagation and the local loading conditions. This directionality of interfacial cracking and the loading phase angle effect seem explainable in terms of the competition between dislocation emission from the crack tip and decohesion of the interface, and relate...

... The authors have shown previously that the presence of a dislocation-free zone (DFZ) between a crack tip and its plastic zone is closely related to the condition for dislocation emission from the crack tip. The local stress intensity at the crack tip is shielded by the dislocations...
