摘要
用求解接触撞击问题的方法对陶瓷／复合材料装甲的撞击响应和失效机理进行数值仿真。着重讨论了接触撞击界面的搜索与确定、接触撞击力的计算、以及失效准则及其处理技巧等３个问题。计算结果与试验结果进行了比较，符合良好。
The impact response and failure mechanism of the composed ceramic/composite armour are simulated numerically by use of the solution method to contact-impact problems. Emphasis is put on the searching and determination of the contact-impact interface between the projectile and armour, the algorithm for the contact-impact force calculation, the establishment of failure criterion and its implementation strategy. The computational results are compared and agreed well with those data resulted from test.
