The extent on mixed-mode stress intensity factor (SIF) of inclined multiple cracks in an unnotched bar has been investigated numerically. Opposite cracks with various crack depth ratios (a/d), crack aspect ratios (a/c) and inclination angles (θ) were considered. The geometry correction factor (Y) was calculated by considering the effect of mode-II and mode-III fracture. It was observed that, for short...
