摘      要：In recent years, the approach of strain energy density （SED） has received special attention in the analysis of notch effect on fatigue strength of notched components, e.g. ref. [1-3]. One of the fundamental contributions to SED-based approaches was by Sih [4,5] who proposed the SED factor S, which was defined as the product of the SED and a critical distance from the point of singularity. Thus, the failure is controlled by the critical value S~.
