Failure Behavior of PZT 95/5 under Direct Current,Pulsed Electric Field and Shock Compression

摘要：

　　Failure behavior of PZT 95/5 under direct current,pulsed electric field and shock compression is studied by experimental and theory analysis in this paper.The electrothermal coupled failure behavior is a key mode when the PZT 95/5 is subjected to direct current.But when the pulsed electric field is applied to the PZT 95/5,the resonance effect and the relation between energy and frequency have been considered,the vibrant energy shifts to high frequency and the possibility of electromechanical-coupled failure behavior is increased with decreasing the pulsed duration.When the pulsed duration is increased,the failure behavior transfers from mechanical coupled with electric failure to direct current mode step by step.The Failure behavior of PZT 95/5 under compression is complex that not only all of failure mechanism in static must be considered but also the microstructures evolvement under shock compression should be considered.
