From the author’s recent studies, it was found that, in low/medium/high cycle fatigue(LHCF) regime, the Wöhler Curve Method is well suitably employed to perform the fatigue life assessment of metals, in which the stress-based intensity parameter calculation is based on the linear-elastic analysis. In this study, an attempt is made through many fatigue test data of notch components of metals from the literature to illustrate that, in LHCF regime, the Notch S-N Curve Method is well suitable for fatigue life analysis of notch components of metals, in which the stress-based intensity parameter calculation is based on the linear-elastic analysis. By concepts of the critical stress and the critical distance by Taylor and by two calibration fatigue failure curves of a smooth specimen and notch specimen by Susmel and Taylor, further, a local approach for predicting the notch S-N curve is proposed based the linear elastic stress fields ahead of notches. Accuracy of the Notch S-N Curve Method is proven by many fatigue test data of notch components of metals from the literature in LHCF regime.
