The paper deals with simulation of fatigue performence of steel elements under uniaxial periodic loading in the high-cycle regime. For this purpose a sinusoidal stress model has been defined which is equivalent in terms of fatigue life to the actual stress given in the form of Fourier series. The equivalence conditions follow from the theory of energy transformations systems and are related to internally and externallydissipated energy by the average shear strain energy and Kevin-Voigt's model of the material. Thereby the cycle couting and use of a fatigue damage accumulation rule is avoided.
