NUMERICAL SIMULATION OF AE IN ROCK FAILURE |
| |
| Abstract: | The basic idea and framework are presented for the numerical simulation of AE in rock failure. Some important problems are discussed briefly with the example of finite element method , such as discretization of elements, assignment of element parameters, and calculation of AE ratio. A practical computation example is given, from whose results the AE sequences for time and space are obtained. |
