| 英文摘要 | In this paper, an improved DDA method proposed by the authors is used to simulate the rock failure process under dynamic loading, and several SHPB tests on Brazilian discs with different angle pre-cracks are conducted for verification. The simulated main crack paths of different specimens agree well with the observations in the SHPB tests. In addition, the perforation process of a hard projectile into rock is also simulated, and some heavily discontinuous phenomena in impact failure are captured. It shows that the improved DDA method is able to simulate the failure behavior of rock under dynamic loading. |
