Implementation of a J-integral based Maximum Circumferential Tensile Stress theory in DDA for simulating crack propagation

Crack propagation is a very important research subject within the field of rock mechanics. In this study, a J-integral based Maximum Circumferential Tensile Stress theory was applied to the conventional Discontinuous Deformation Analysis (DDA) Method for simulating crack propagation. First, according to the relevant theories of fracture mechanics, a crack propagation theory suitable for DDA was derived by calculating J-integral in DDA...
