The fatigue life of materials and structural details can be characterized by distinct fatigue regimes. These regimes may range from quasi-static monotonic loading to very high cyclic fatigue. The Kohout-VÄchet (KV) fatigue model describes the damage regimes since the limiting tensile strength to the permanent fatigue limit. In this paper, the fatigue S-N response of the P355NL1 steel, using smooth specimens under uniaxial stress states, is characterized based on the original suggestion by Kohout and VÄchet. The experimental results related to the fatigue behavior of the P355NL1 steel were obtained through fatigue tests under stress-control conditions, covering distinct stress ratios. This study validates the importance and applicability of the global S-N models to describe the Wöhler S-N curve, from tensile strength to the fatigue limit, in the fatigue life evaluation of structural details.
