| Abstract: |
| Based on the references [1,2] the parametric variational principle for Rigid Finite Element Method is put forward and proved in this paper. Using the method presented here for elasto-plastic analysis, the computational work will be considerably reduced and the accuracy will be improved. Furthermore, the method can easily consider the non-associated flow rule and provide an efficiency approach for stability analysis of rock structure. |
