\begin{abstract}
From the author's recent studies, it was found that, in low/medium/high
cycle fatigue(LHCF) regime, the W\selectlanguage{ngerman}öhler Curve Method is well suitably
employed to perform the fatigue life assessment of metals, in which the
\textbf{stress-based intensity parameter} calculation is based on the
\textbf{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 \emph{stress-based intensity parameter} calculation
is based on the \textbf{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.%
