The damage of non-persistent rock discontinuities and hydromechanical effects are two key phenomena in rock mass stability. Based on experimental results (literature), a new constitutive damage-plastic joint model has been proposed to model fracturing in quasi-brittle materials along a predefined surface. This model, takes into account the progressive degradation of strength and stiffness of joints in both normal and tangential directions. It considers irreversible relative displacements, tangential residual strength and the nonlinear behavior of joints. The model reproduces well the experimental results when implemented in the finite element code CESAR-LCPC. In order to performing coupled hydromechanical analysis, a computing module of sta...
