| 摘 要： | 在二级氢气炮上，对钨合金进行了冲击／再冲击、冲击／卸载实验，通过ＶＩＳＡＲ测试技术测量了样品／窗口界面的粒子速度波形。得到了钨合金材料在高温高压下剪切模量随压力的变化，实验结果表明，在０～２００ＧＰa的压力范围内，钨合金的剪切模量随压力的变化近似为二次曲线变化，将实验结果与用Ｓteinberg本构关系计算的剪切模量Ｇ进行了比较，二者结果符合较好。

| Abstract: | At the two stage gas gun,by using the methods of loading/reloading and loading/unloading,by means of mearsuring the interface velocity between sample/window through VISAR technique,we obtained the variation of shear modulus of tungsten alloy with the pressure under shock loading.The results show the relation between the variation of shear modlus with pressure is approximately square curve,when we compare the experimental results with the calculated results by Steinberg model,they are in accord with each other. |
