Abstract
The simulation of crack propagation by mean value method (MVM) is discussed, in which advanced refining and remeshing strategies are proposed and then used. Two benchmark problems are analyzed by MVM and compared with standard FEM. It is found that MVM can provide significantly better accuracy in both displacement and energy norms. Numerical results of fracture problems are found to be good agreement with experimental solutions. Furthermore, it is observed that mesh can be automatically refined and remeshed along the propagating crack paths.
