摘要 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 stress-strain curves for a special steel and a WMo alloy have been measured by using the split Hopkinson pressure bar (SHPB) technique where the bar was of 3.17mm in diameter. Through the test process observation and the result analysis, some issues encountered in the tests at high strain rates are discussed.
