A new method is proposed to evaluate the strength of a sharply notched structure with a large notch angle. A new parameter, Ke which is to be called the equivalent stress-intensity factor and which prescribes the singularity of stress distribution near the notch tip, is defined to evaluate the effect of a sharp notch on the fatigue and static strength. This method enables one to predict the strength of a notched structure by using the well-known parameters ΔKth and KIC. Fatigue tests of HT60, SS41 and a brittle fracture test of an acrylic plate were conducted and the applicability of the parameter was verified.
