Shock-induced depoling of the ferroelectric ceramic PZT 95/5 is utilized in pulsed power applications. Experiments to examine the shock response of normally poled PZT 95/5 under uniaxial strain conditions show that depoling kinetics, as reflected in current generation through an external circuit, is inhibited by both decreasing the shock pressure and increasing the electric field within the ceramic. A model to describe the response of the ferroelectric ceramic has been developed and implemented into simulation codes. Measured currents in the external circuit and transmitted waveforms at a window interface have been compared with results from simulations for experiments with shock pressures varying from 0.6 to 4.6 GPa and electric fields varying from 0.3 to 37 kV/cm.
