| Abstract: | In this paper, the effective stress for multi_porosity elasticity model is presented by means of stress analysis for double porosity media elements. It is found that the effective stress law is not unique, it depends on the hypothesis of constitutive equations for multi_porosity media. Diversified effective stress laws for multi_porosity are developed. |
