On the complementary roles of anisotropic crack density and anisotropic crack driving force in phase-field modeling of mixed-mode fracture
This study elucidates the distinct and synergistic roles of anisotropic crack density and anisotropic strain energy in phase-field modeling of mixed-mode fracture, demonstrating that while crack density primarily governs the fracture path and resistance, anisotropic strain energy controls the driving force and significantly influences elastic stiffness and peak load in stress-concentration geometries.
