Coupled Wave Processes in Piezoceramic Bodies Generated by an Electric Discharge

Boundary-value problems of the unsteady-state deformation of piezoceramic bodies by an electrical discharge are formulated by generalizing the Rompe-Weizel capacitor-discharge theory. A detailed analysis of the wave field produced by a discharge in a cylindrical spark generator is presented. The relationships governing the variation of the current pulses and of the electrical potential difference in the course of the discharge and during the subsequent time instants are investigated. The results obtained by generalization of the capacitor discharge theory are compared.
