What is fatigue life calculation?

Fatigue life calculation of a varying load spectrum is a complex task. There are various approaches suggested to simplify the load spectrum into simple major and minor cycle. One such approach is rainflow counting methodology. In this paper, a new Microsoft Excel-based algorithm for the modified graphical rainflow counting method is presented.See all results for this questionTheory reference | FatigueToolbox.org3. Fatigue stress calculation. For fatigue calculations, in particular the cycle counting process, only one stress component must be selected or a fatigue effective stress must be calculated. Selecting a stress component, e.g. is straight forward, however this is only meaningful in certain cases, where the global coordinate system is appropriately oriented in relation to the fatigue critical analysis of revised fatigue life calculation algorithmStress Life Fatigue.xls - ExcelCalcsPurpose of calculation: Fatigue design of cast or wrought iron and steel.
