WebbThe rain-flow-counting algorithm (also known as the “rain-flow counting method”) is used in the analysis of fatigue data in order to reduce a spectrum of varying stresses into a set of simple stress reversals. 1. The fatigue phase of a product’s life cycle bath tube curve is characterized by an increasing failure rate. 2.
WebbThe rainflow method allows the application of Miner's rule in order to assess the fatigue life of a structure subject to complex loading. The resulting tabular data is sometimes referred to as a spectra. Algorithm 1. Reduce the time history to a sequence of (tensile) peaks and (compressive) troughs. 2. Imagine that the time history is a pagoda. 3. Webbstress history and use the Rain Flow Counting Method as a basis for the calculation of the fatigue damage. Stress range histories General Real life structures prone to fatigue will experience stresses that vary with time, often in a very complicated manner. These stress histories are generally the results of an irregular load history and
