The Application of PVDF on the Study of Dynamic Mechanics Property of Layered Medium
Abstract:In this paper, the basic theory, the demarcate and the stress testing system of PVDF in the SHPB experiment are introduced. The research demonstrates that the performance of the testing system is steady, the demarcated curves’ linetype is good, and the dynamic responding time is short. At the same time,stress attenuation is tested and analysed with PVDF when the stress wave gets accoss the layered medium.
