Other AbstractA new method for describing damage of brittle material and a new strength criterion applicable to heterogeneous material such as rock and concrete are proposed. This criterion is called criterion of strain strength distribution in which strain is used as the measurement of strength. A homogenized representative volume element (RVE) containing cracks is introduced with the basic assumption that strain strength complies with a certain distribution law. The concepts of intact degree and fractured degree are proposed to representing the damage ratio of material quantitatively. Intact part of RVE maintains elasticity, while fractured part is described with contact theory in mesolevel. Based on the ideas above, a generalized formulation to tensile failure, shear failure and failure under joint effect of tension and shear is established and a new progressive failure criterion to describe macro deformation and fracture of brittle material is formed.
