Crack Propagation Analysis of Compressive-Shear Mixed Mode by Meshless Method |
| |
| Abstract: | The meshless method is used to model the state of contact impact, slippage and freedom for cracks in rock structures which compressive stressed are added to, and stress intensity factors are calculated for wing cracks. Single and double crack propagations are analyzed and simulated. The numerical examples show that the method given is effective and feasible. |

| Keywords: | meshless moving least square compressive shear mixed mode crack crack propagation |
