“…When this sampling variability is included in the analysis, the fatigue damage estimated by spectral methods becomes a random value with a statistical variability evaluated through confidence intervals. Although some achievements have been obtained recently [84], this topic certainly deserves more attention by research in the years to come.…”

The frequency domain techniques (also known as “spectral methods”) prove significantly more efficient than the time domain fatigue life calculations, especially when they are used in conjunction with finite element analysis. Frequency domain methods are now well established, and suitable commercial software is commonly available. Among the existing techniques, the methods by Dirlik and by Tovo–Benasciutti (TB) have become the most used. This study presents the historical background and the motivation behind the development of these two spectral methods, by also emphasizing their application and possible limitations. It further presents a brief review of the other spectral methods available for cycle counting directly from the power spectral density of the random loading. Finally, some ideas for future work are suggested.
