Progressive damage analysis of open-hole composite laminates under compression load

  • 摘要: 首先,针对纤维增强复合材料开孔层板进行了压缩试验,通过微距数显设备、电镜扫描和X光扫描设备检测了加载过程中的渐进损伤和试验件最终破坏模式,观测了损伤起始和45°与90°铺层间的分层现象. 其次,将复合材料开孔层板失效分为层内失效和层间失效,基于细观损伤力学MMF3理论和界面胶层单元方法建立了开孔压缩损伤跨尺度分析模型.最后,应用该模型对开孔压缩损伤起始、损伤扩展和层板破坏模式进行了预测,获得了纤维和基体损伤起始位置、分层产生位置及扩展过程、最终的分层和压入破坏等计算结果.计算结果与试验结果获得了较好的吻合,表明该计算模型适用于分析复合材料开孔压缩渐进损伤问题.
