On the use of theory of energy transformation systems in fatigue calculations of steel elements
Abstract
The paper deals with simulation of fatigue performance 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 transformation systems and are related to internally and externally dissipated energy by the average shear strain energy and Kelvin-Voigt's model of the material. Thereby the cycle counting and use of a fatigue damage accumulation rule is avoided.
