The material belongs to elastic-plastic model.
According to Mohr-Coulomb yield criterion adopted in this paper, whether the material reaches damage state is judged by internal stress state, and the material is processed by elastic model if it does not reach damage state, and otherwise it is processed in accordance with the elastic-plastic theory[7].
