The irreversibledeformation and fracture of solids may be related to a class of processes in which the macroscopic effects are predominated by mesoscopic level behavior.
固体的不可逆形变和断裂与一类过程相关，在此过程中宏观效应是细观层次行为起着支配作用。

From the viewpoint of thermodynamics, this process from rock deformation, failure to collapse is an irreversible process of energy dissipation, including both energy dissipation and energy release.
Moreover, the irreversible plastic deformation of rock increased, and at the same time, the fracture deformation of rock gradually increased, which was produced by cyclic load.
