Abstract: This manuscript presents the fracture behaviour of a slanted edge cracked plate with a circular hole subjected to various in-plane loadings, such as tensile, shear and combined (tensile and shear) loadings, through the mixed mode stress intensity factors (MMSIF). There is a lack of work in the direction of calculating the fracture behaviour of the slanted crack under the influence of a hole subjected to the various in-plane loadings. In this work, the crack is modelled using extended finite element method (XFEM) under plane strain condition using MATLAB. The MMSIFs are increased with the increment in the crack length but as the crack angle is increased the Mode-I SIFs are decreased whereas Mode-II SIFs are increased. The SIFs are critical for the plate with a hole as compared to the plate without a hole. The values of MMSIFs are the highest for the plate under combined loading and the least under tensile loading.
