摘　　要：复合材料已被广泛应用于各个领域,分层破坏是复合材料主要的破坏形式之一。对复合材料分层失效分析中主要的方法粘聚区模型进行详细的阐述。首先介绍了粘聚区模型发展历史、界面强度参数和本构关系的研究现状并对存在的问题进行了分析,然后对该模型在复合材料层间失效分析应用现状进行了阐述,重点分析了该模型在有限元应用中存在的问题。研究表明,近年来,CZM已逐步成为复合材料分层失效研究的主要方法,但在应用中需要解决强度参数确定准确性、计算收敛困难和计算效率不高等问题。Composite has been widely applied in different fields,and the delamiantion failure is one of the main failure. In this paper,the development of composite delamiantion failure based on the cohesive zone model（ CZM）is presented. First,the development history of CZM,the research status of strength parameters and constitutive relation are introduced and the existing problems are analyzed. Second,the application status of CZM in the composite delamiantion failure anlysis is present and the existing problems of this model applied in the finite element method are introduced. The research result shows that although the CZM is the main method to analyze the composite delamiantion failure, the problems of the prediction accuracy of parameters, convergence difficulties and low calculation efficiency should be solved.
