“…Therefore, there is no need for a crack tracking algorithm or additional criteria for crack branching and merging. The method has found its extension in subjects such as composite failure [1,6,58], ductility [2,4,28,36,60], dynamic fracture [10,14,41,57], hydraulic fracture [11,26,54,55,61], and environment assisted failure [35,48] to name a few. When mechanics of natural materials is concerned, especially geomaterials, they often exhibit anisotropic behaviors [3,16,44].…”
