| 摘 要： | 构建了由刚性元、弹簧元和二维板元构成的准三维有限元模型,发展了一种考虑层间应力的、多向层压板静强度分析方法,包括应力分析、失效分析及材料性能退化三个主要部分,能够模拟面内和层间损伤产生、发展直至层压板整体破坏的完整过程,并得到强度值.对两种复合材料层压板进行了实际计算,静强度预测结果与试验结果吻合较好,同时预测并给出了损伤的分布及其在不同载荷下的演变过程.

| Abstract: | A evaluation procedure for the static strength analysis of multidirectional composite laminates was established with a quasi-3D finite element model incorperating plate elements,spring elements and rigid elements.The procedure is the integration of in-plane and interlaminar stress analysis,failure analysis and material property degradation.The analysis of two kinds of composite laminates demonstrates a good agreement of strength prediction with the experiments,and the distribution and evolution of damages w... |
