| 摘 要： | 以钨球侵彻装甲板试验研究结果为依据，运用牛顿第二定律，对不同弹靶条件下靶板材料的动态屈服强度进行了计算．结果表明，靶板材料的动态屈服强度并非常数，而与靶板厚度有直接关系，进而对极限穿透速度计算公式中靶板材料动态屈服强度一项进行修正，采用修正公式可获得与试验数据相符的结果．

| Abstract: | Using Newton second law, this paper calculates the dynamic yield strength of target material under variable projectile target conditions, in the base of experiments result that tungsten spheres penetrate RHA targets, the results show that the dynamic yield strength of target material is not constant, but variable with target relative thickness. Then critical penetration velocity formula is modified about the dynamic yield strength of target materials, using the modified formula, it can be calculated that accords with experiment result. |
