被动围压下PBX的冲击动态力学性能
Impact Mechanical Properties of PBX in Passive Confined Pressure
摘要
Abstract
The dynamic mechanical properties of PBX in confined pressure were studied by passive confined pressure test methods of split hopkinson compressive bar (SHPB) aluminum jacket and PBX based on TATB. The yield strength of PBX under different strain rates were obtained. The results show that with enhancing the strain rate,the yield strength of PBX enhances,PBX bears higher stress than unconfined state,exists visible plastic strain and samples does not happen obvious failure.关键词
