A new continuum damage model is proposed based on homogenization of cohesive micro-cracks in an elastic representative volume element (RVE). A novel damage model is developed to model progressive microrupture and material degradation through cohesive micro-crack coalescence and nucleation. The newly proposed model includes a macro-level yield potential function and the corresponding damaged evolution law, which describes a pressure-sensitive elasto-plastic material at macro-level.
