Abstract: 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.

Key words: composite, delamiantion failure, cohesive zone model (CZM)
