7. An Electrically Conducting Interface Crack Between Two Piezoelectric Materials

An electrically conducting model of interface crack between two piezoelectric materials is studied in this chapter. This model should be used for cracks whose faces are covered with electrodes or for cracks filled with a conductive fluid. At the beginning, the presentations of the electromechanical quantities via sectionally analytic vector functions obtained in Chap. 4 are reformulated to another form that is the most convenient for the analysis of the problems connected with electrically conducting boundary conditions. It is then assumed that the bimaterial’s components are polarized in the direction orthogonal to the crack faces and loaded by remote tension, shear forces, and the electrical field parallel to the crack faces.
