APPLICATION OF INTEGRODIFFERENTIAL EQUATIONS FOR THE PROBLEM OF ELECTRICALLY PERMEABLE CRACK ON A PIEZOELECTRIC-CONDUCTOR INTERFACE

A plane strain problem of a crack on interface between an isotropic elastic conductor and a transversely isotropic piezoelectric ceramics is considered. The problem is reduced to system integrodifferential equations on the interface. These equations relate the normal and tangential components of the crack opening vector with distribution of normal and shear stresses on the crack surfaces. It therefore make it possible to obtain an exact solution as a function of the loading applied to the crack surfaces. As an example, some analytical solutions of the crack problem are given.
