Comparison of results of stress cycle counting by the direct spectral method and the Fu-Cebon method for bi-modal type stress processes

This article compares the results of a high cycle fatigue analysis obtained through the application of the two methods dedicated to analysis of response of the structure of the bi-modal type – the direct spectral method and the Fu-Cebon one. the compared parameter is the lifetime for an assumed material S–N curve and stress spectrum defined in an article by Fu & Cebon.
