Because of the low tensile strength of brittle materials, the tensile fracture simulation is of great importance to the numerical study of the failure procedure of these materials. A simple element-splitting model is proposed in this paper to simulate the tensile fracture procedure based on finite element method (FEM). As an application of this model, the fracture procedure of a doughnut-shaped specimen is simulated and the numerical results are compared with the deformation fields' evolution from an experiment on a granite specimen with the sa...
