The microstructure of a material significantly impacts its fracture behavior, but it can be difficult to quantify the impact of microstructure on fracture. The phase field method provides a powerful tool for modeling fracture because it can both determine the crack path and capture the creation of new free surfaces. It also provides an easy means of having locally varying fracture properties to include the impact of microstructure. However, currently all phase field fracture models assume isotropic elastic properties and thus miss the impact of heterogeneous stress distributions due to crystallographic texture, A new phase field fracture model has been developed for brittle materials that considers anisotropic elastic properties of the materials, in addition to considering the impact of microstructure. This model has been implemented using the MOOSE finite element framework. In this presentation, we summarize our approach and demonstrate its capability.
