Abstract Based on the properties of rock different from concrete under blasting loads，the state equation of RDCDMC is improved. The volumetric deformation of plasticity is taken into account in the definition of tension and the tension-failure rule is adopted. The results of numerical simulations for explosion-induced wave by tamped mili-explosive charge indicate that the improved model is capable of describing the response of the inelastic region of granite and available in numerical simulations on propagation of stress wave.
