| 摘 要： | 基于有限元方法,对受轴向压缩的复合材料开口曲板进行渐进失效分析。采用三维 Hashin 准则和 Ye准则作为纤维损伤、基体损伤、分层损伤判据,通过非线性刚度退化模型来模拟损伤演化过程,获得了开口附近损伤扩展过程。数值模拟结果与文献试验结果对比,取得了较好的一致性。

| Abstract: | Based on the finite element method,composite panel with cutout subjected to axial com.pression load , progressive failure analyses results are presented. Three-dimensional Hashin failure cri-terion and Ye failure criterion were adopted as material damage initiation criterion for fiber failurematrix failure and delamination failure, and nonlinear material degradation scheme was applied tosimulate the damage evolution. The damage evolution process is discussed. The numerical simulationresults are in good agreement with the experimental results. |
