A phase-field regularized cohesive zone model for quasi-brittle materials with spatially varying fracture properties

This study develops a numerical method combining the phase-field regularized cohesive zone model (PF-CZM) and random fields for modeling of complicated mesoscopic fracture in quasi-brittle materials. In this method, the material’s fracture properties such as tensile strength and fracture energy are assumed as spatial random variables and represented by Weibull random fields (RFs), which are mapped to finite element meshes. The PF-CZM with...
