Plastic Stress

In this study, the effects of biaxial load on the elastic-plastic stress concentration factor and the plastic zone size of the circular hole are investigated, and the elastic-plastic stress and strain fields of the crack emanating from the circular hole are calculated in the process of crack growth. The elastic-plastic stress concentration factors for various biaxial load ratios are obtained. In order to provide a reference for structural damage monitoring, the variation characteristic of strain at crack front ligament are analyzed in the process of the crack growth.
