Before revision: Rainflow counting identifies the closed cycles in a stress-strain curve The rainflow-counting algorithm is used in the analysis of fatigue data in order to reduce a spectrum of varying stress into an equivalent set of simple stress reversals.
After revision: Rainflow counting identifies the closed cycles in a stress-strain curve The rainflow-counting algorithm is used in calculating the fatigue life of a component in order to convert a loading sequence of varying stress into an equivalent set of constant amplitude stress reversals.
