| 摘 要： | 本文在圆柱形弹撞击刚性靶板的实验研究基础上,依据几种理论分别对实验结果进行了分析处理,给出了在实验速度范围内紫铜和D60钢的动态屈服应力随撞击速度的变化曲线.从实验结果得知,两种材料在不同撞击速度范围内其动态屈服应力的敏感度不同.并对实验中试件出现的双锥等现象进行了初步分析,同时提出了进一步的研究意见.

| Abstract: | In this paper, on the base of experiment research for cylindrical projectiles striking against a rigid target, the experiment results are analysed and processed respectively according to various theories. The dynamic yield stress curves of copper and 60~# steel against the impact velocity are obtained in experimental scope. It is known from experimental results that the sensitivity of dynamic yield stress of the two materials within different impact velocity zones are differed. The double-cone phenomena and others of samples are preliminarily analysed. The further suggestions on experiment are proposed. |
