摘要：
A novel three-dimensional progressive damage model based on generalized mixed finite element method (GMPDM) was established to investigate the strength and failure behavior of notched composite laminate plate. Firstly, the stress distribution of notched isotropic plate under tension is studied, and the results are compared with the analytical solution to verify the high accuracy of the generalized mixed finite element method. Then, the strength and failure modes of three notched composite laminates are studied. The results are compared with the several groups of results to verify the high-precision of the developed GMPDM method, respectively.
