| 摘 要： | 复合材料结构界面失效分析有助于复合材料整体化结构细节设计,有必要进行界面失效问题分析.针对复合材料整体化结合界面进行有限元数值模拟失效分析方法研究,对承受不同载荷的结合界面选用不同的建模方法和失效模型.对于层压板失效,在Tsai-Hill判据基础上,增加破坏能判据;对于界面失效,提出基于应力、应变和破坏能的多级判据及其衰减方法.结果表明：本文方法建模简单、计算速度较快、计算结果与试验值吻合性好,可为复合材料整体化结构设计提供工程实用的分析方法.

| Abstract: | Numerical finite element modelling techniques and failure analysis methods for integrated composite joint interface were studied. Different modelling techniques and failure models were adopt for joint interfaces bearing different loadings. The rule for defining interface mechanical properties was prescribed based on comparison between test results and simulations. The research of this paper can provide engineering utilizable analysis method for integrated composite structure design and analysis. |
