Description
Load-time histories acting on structures are often irregular, i.e. it is a so-called variable amplitude spectrum. To perform a fatigue analysis it is required that such a history is translated to cycles: number of occurrences, stress amplitude and mean stress level.
The method of extracting cycles giving the most realistic results is the Rainflow Counting method since it combines the highest peaks and lowest valleys in a spectrum with each other.
