This paper deals with the reformulation of the Modified Wöhler Curve Method to make it suitable for being used along with nominal stresses to design notched components against constant/variable amplitude multiaxial fatigue loading. The accuracy of this design methodology is checked against a large number of experimental results taken from the literature. The outcomes of the performed validation exercise strongly support the idea that the proposed approach can safely be used to perform the multiaxial fatigue assessment of notched structural components. This holds true also when the necessary fatigue strength reduction factors are estimated via standard, classic formulas.
