Abstract:

建立一个有效的计算模型,以分析复合材料层板在静压入过程中发生分层、纤维断裂的现象。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。对炭纤维增强环氧树脂基复合材料层板在静压入过程中发生的分层和纤维断裂现象进行预测,并与实验结果进行比较;对炭纤维增强双马来酰亚胺树脂基复合材料层板在静压入过程中的分层损伤和最终破坏接触力的大小进行预测,并与低速冲击下的结果进行比较。数值仿真与实验结果吻合较好,表明静压入分析方法是复合材料层板在低速冲击下产生损伤的可替换分析方法。
