AB  - The main aim of the current study is to explore direction-dependent fracture initiation and propagation within an arbitrary anisotropic solid. In particular, the specific objective is to develop an anisotropic cohesive phase-field (PF) fracture model. The anisotropy in fracture due to mixed- mode conditions. A power law-inspired fracture criterion is adopted and it captures the dominating mode behavior of fracture. A volumetric-deviatoric energy split has been implemented to capture the impacts of mixed modes. The performance of the model is demonstrated through numerical examplestopredict anisotropic fracture in quasi brittle materials such as rock and wood under mixed modeloadingconditions.
