DISCHARGE OF PZT95/5 FERROELECTRIC CERAMICS UNDER TILTED SHOCK WAVE COMPRESSION

摘要

The current waveform of Ferroelectric ceramics PZT 95/5 depoling under tilted shock wave compression has been studied. An analytic model was established to analyze the effects of incident angle on the rising time, duration and peak amplitude of the depoling current. Experiments were conducted as well to confirm these effects. Results indicated that with the increasing of incident angle, the depoling current rises more slowly, the pulse duration becomes broader and the peak amplitude remains constant until the waveform decays into a triangular form.
