The damage theory is used to study the crack tip problem and the crack tip damage field is obtained. A near-field damage criterion is proposed based on micro experimental analysis. The relationship between the macro fracture parameter and the microstructure parameter of material has been obtained an

In this paper, based on the three-dimensional flow theory of plasticity, the fundamental equations for the plane strain problem of elastic-perfectly plastic solids are presented. By using these equations the elastic-plastic fields near the crack tip growing step-by-step in an elastic incompressible-
