摘要：
In order to study the fracture process of rock-like materials for structural safety, a method is developed to simulate two-dimensional (2D) and three-dimensional (3D) crack growth. The novelty of the developed method is that a procedure is used to consider stress redistribution due to cracking during the fracture process simulation within a loading step. Based on this way, the instable competitive and coupling fracture process can be simulated by considering the coupled interactions among cracking within rock-like materials. As case study, 2D and 3D fracture processes of a rock-like specimen containing pre-existing flaws were simulated and compared with the corresponding experimental results. From the comparison of simulation and experimental results, it can be determined that the agreement between experimental and numerical fracture modes was excellent, which supported to assess the effectiveness of the developed method. The method can be used to predict crack path of rock-like materials for studying their fracture characteristics.
