A modified phase field model for predicting the fracture behavior of quasi‐brittle materials

Phase field models have a very good capability in predicting the crack path, but most of them represent the dependence of the regularization parameter on the load‐carrying capacity of structures. In this paper, a phase field model is coupled with isotropic damage model aiming to resolve this issue in the fracture simulations of quasi‐brittle materials. Damage variables are calculated by a continuum damage mechanics model based on accurate energy...
