Note on cycle counts in irregular loads
Web4.1 Cycle counting is used to summarize (often lengthy) irregular load-versus-time histories by providing the number of times cycles of various sizes occur. The definition of a cycle … WebAug 29, 2024 · ‘Rainflow Counting’ is a method to determine the number of fatigue cycles present in a load-time history. A fatigue cycle is the loading and unloading of a part as shown in Figure 1. With enough repeated cycles, a part will weaken and eventually fail. Figure 1: A load-time history with one fatigue cycle highlighted
