Micro Abstract:
Directional dependency of the fracture resistance, which is observed for a wide range of materials, requires the integration of anisotropic behavior in approaches for crack growth simulations. The gradient term in the energy functional of a phase field model for isotropic brittle fracture is enhanced accounting for an anisotropic material resistance. Results of crack path simulations for different samples are presented to show the accuracy of the proposed model.
