Deep underground rocks exhibit significant layered heterogeneity due to geological evolution and sedimentation. Rock fracture toughness, as one of the important indicators hydraulic crack propagation, also exhibits heterogeneous distribution. In order investigate influence non-uniform toughness on this paper establishes a planar three-dimensional propagation model. The model is numerically solved using 3D displacement discontinuity method (3D-DDM) finite difference method. calculation...
