Using a finite element method, in conjunction with an equivalent domain integral approach, the elastic-plastic crack-tip J-integral is computed for semielliptical surface flaws in a plate under a remote tensile load. The computed elastic-plastic values of the J-integral are compared to the elastic o
The weight function for the surface point of a semi-elliptical crack in a plate of finite thickness has been derived and tested against numerical data available in the literature. Derivation was accomplished by using the universal weight function form and two reference stress intensity factors. It w
In bending of a finite cracked plate, the stress intensity factor (SfF) at a cracked tip is usually negative. This means that the displacement at the vicinity of the crack tip is overlapped. However, this is not reasonable. In this paper a simple model is suggested. When the SIF is negative, some pa
