利用小直径(3.17mm)的SHPB系统初步获得两种较高强度材料(一种特种钢和一种WMo合金)应变率达到104s-1以上的动态压缩应力 应变曲线。通过对这次实验过程及结果的观察和分析,对高应变率实验存在的几个问题进行了探讨。
The dynamic compressive stress-strain curves of two higher-strength materials (a special steel and a WMo alloy) with a strain rate of over 104s-1 were obtained by using a small diameter (3.17mm) SHPB system. Through the observation and analysis of the experimental process and results, several problems existing in high strain rate experiments are discussed.
