Notes:
In the virtual crack closure method (VCCM), the energy release rate is computed based onthe results of finite element calculation, and the stress intensity factor (SIF) is computed from theenergy release rate. In this paper, the stress intensity factor of mixed-mode surface cracks under threepoint bending is studied by using the three dimensional modified virtual crack closure method(MVCCM). The modified virtual crack closure method is required to open one element face areawhose shape is arbitrary and finite element widths are unequal across the crack front. The effect of thedistance between the location of load and crack face, crack shape and crack depth to the stressintensity factor is also discussed, along with practical results and conclusions
