摘要 对近年来复合材料分层问题的粘聚区模型研究现状及其在整体复合材料结构元件连接界面的失效评估中的应用情况进行了简要的评述。重点指出了在目前的研究工作中存在的两类主要问题:(1)复合材料层间粘聚区模型有待解决的一些基本问题;(2)基于粘聚区模型元件连接界面的复杂失效机理模拟问题。最后指出了进一步开展的重点研究方向。 The state-of-the-art in the state of the cohesive zone model for modeling the delamination of laminated composites is reviewed and its failure analysis of the joint interfaces of elements in integrated composite structures in recent years are described. Two kinds of challenging problems are recognized as follows: (1) the fundamental issues in the cohesive zone model for modeling delamination in composites: (2) the modeling of the complicated failure mechanisms of the joint interfaces of elements in integrated composite structures. Finally some key research directions developed in the future are suggested.
