该计算模型基于有限元程序的三维逐渐损伤理论对层板的静压入全过程进行模拟,对逐层逐个单元的损伤进行判断,可以模拟任意角度、铺层厚度的层板在递增载荷下的逐渐损伤破坏过程。

The method uses the 3D progressive damage theory and analysis technique.

该方法应用三维逐渐累积损伤理论和分析技术,对层合板的冲击以及冲击后含损伤的层合板在压缩载荷下损伤扩展的全过程进行分析,分析中没有对冲击后层合板的损伤状态做人为假设,而是把冲击后层合板的预测损伤直接用于剩余压缩强度研究,从而不仅提高了最终失效载荷的预测精度,而且避免了为获得冲击后损伤状态参数所进行的大量试验,同时开发了模拟程序,该程序可以预测任意铺层角度、铺层厚度的层合板受外物冲击以及冲击后的损伤状态及在压缩载荷下的逐渐损伤破坏过程和最终失效载荷。
