Abstract: The nonlinearty of rock deformation results mainly from closing, opening, and propagation of microcracks or microviods inside rock. Taking the influence of microdefects into account, a new constitutive relationship of damage is developed, and applied to different models of rock with different porosities. The theoretical curves consist with the experimental ones.
