- Abstract
Predicting the failure behavior of composite materials is of great significance to the design of composite structures. Due to the complexity of its failure mode and failure mechanism, the traditional computational fracture mechanics method and the numerical method based on damage mechanics are difficulty to model modeling its failure behavior. The phase field method combines the advantages of fracture mechanics and damage mechanics. It can accurately capture the crack initiation, propagation and kink behavior without additional criteria. Recently, it has been widely used in the failure analysis of composite materials. In this paper, the basic theory of phase field method was briefly introduced, and the fundamental fracture energy model and governing equations were given. Following that, the review focused on the research progress of composite failure analysis based on phase field method. The application ranges of phase field method on composite material field were reviewed. Finally, the damage simulations of composites under fatigue, hygrothermal environment and impact by using phase field method were discussed.
