| 摘 要： | 利用能量法建立平头弹贯穿陶瓷/金属复合装甲的分析模型.假定在贯穿过程中弹丸的动能被弹体、陶瓷板和金属背板3部分吸收.该模型考虑了弹体的销蚀与墩粗变形，陶瓷板的压碎与剪切破坏以及金属背板在不同厚度下的破坏模式.在给定的弹靶条件下，可以预测靶板的弹道极限及弹体的残余速度.模型计算结果与相关实验数据吻合较好.

| Abstract: | An analytical model was presented herein for the perforation of ceramic/metal composite armors struck by flat-nosed projectiles using energy balance method. It was assumed that the kinetic energy of a projectile was absorbed by projectile, ceramic tile and backup metal plate during the perforation process. Erosion and deformation (mushrooming) of projectiles, compression/fragmentation and shear failure of ceramic tiles as well as failure modes of backup metal plates with different thicknesses were considered in the present model. For a given projectile and ceramic/metal composite armour, the model can be used to predict the ballistic limit or the residual velocity. The present model predictions are in agreement with now available test data. |
