A review was presented of analyses in which plastic flow in the vicinity of an interfacial crack was treated as the nucleation and glide of discrete dislocations. Attention was confined to cracks along a metal/ceramic interface; with the ceramic being idealized as rigid. Monotonic and fatigue loadings were considered. Attention was focused on the stress and deformation fields near to the crack tip, as predicted by discrete dislocation plasticity. Comparisons were made with those obtained using conventional continuum plasticity theory.
