The intrinsic coupling between the mechanical and the electric \_elds assigns a unique feature for the fracture in a piezoelectric solid[ We model the kink of a crack by continuous distribution of edge dislocations and electric dipoles[ The problem admits an approach based on the Stroh formalism[ A

A kinked semi-infinite,crack in an anisotropic mateeal is analyzd. The stress intensity factors of the kinked crack tip are expressed in terms of those associated with the main crack prior to kinking. The asymptotic stress tield around the crack tip is derived for the degenerate case in which the tw
In this paper\ a method is presented to calculate the plane electroΓelastic \_elds in piezoelectric materials with multiple cracks[ The cracks may be distributed randomly in locations\ orientations and sizes[ In the method\ each crack is treated as a continuous distributed dislocations with the dens
