Abstract: A 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 d... More
