AbstractEnergy function with fracture energy, frictional energy, kinetic energy and elastic energy is proposed. And dynamic equations for continuum-discontinuum model in solid are obtained with the energy function and progressive failure constitutive model based on strain strength distribution. Combined with spring element model, computational scheme for spring force and nodal force in continuum-discontinuum element method is established with consideration of energy dissipation. Relationship between continuum mechanics model and discrete particles are discussed and the critical parameters are determined. Characteristic fracture length in representative volume element (RVE) is introduced, and theoretical expressions for progressive failure process of the element are given. Numerical examples such as uniaxial compression and uniaxial tension test are calculated with this model for verification.
