Abstract

Anti-plane non-stationary boundary problem of electroelasticity for unlimited piezoceramic media consisting of a tunnel cavity is considered. The medium excitation is fulfilled by impulse changes of electrical potential differences applied to the electrode system located on the cavity surface. A system of integro-differential equations of the second type realized by the quadrature method is obtained. Results characterizing changes with time of the total electric charges on the electrodes of various areas of the electrode plating and also the evolutionary development of displacement on the cavity boundary are given.
