The fracture behavior in all fracture mode (AFM)-specimen with a single edged crack under different loading conditions is investigated by the aid of the commercial ANSYS code. The separated strain energy release rates (SERRs) along the crack front are calculated by the modified virtual crack closure integral (MVCCI)-method. It is shown that the computational results of the AFM-specimen are in good agreement with some available findings for pure mode I, mode II, mode III, and mixed-mode I+III loading conditions. Furthermore, the crack growth problems under complex mixed-mode II+III loading condition by using the AFM-specimen, are investigated and results show that once mode II and mode III loads are superimposed, the distributions of the SERRs values are no longer symmetric with respect to the middle point of the crack front. The maximum total SERRs value occurs at z/t =0.5. It can therefore be predicted that under mixed-mode II+III loading condition, fracture will initiate at one corner along the crack front of the AFM-specimen.
