| Abstract: | Visualized numerical simulation the process of rock breaking was carried out by coupled finite-discrete elements method.Through calculating data from Brazilian disc test,the failure mechanisms and failure patterns of rock and the whole failure process of rock from initiation and propagation of cracks to completely breaking were represented.The numerical results showed that the coupled finite-discrete elements method is suitable for the analysis of deformation and failure process of rock. |
