Fatigue Testing with FlexPro: Counting Procedures
Counting procedures like the Rainflow counting procedure have proved to be an invaluable analysis tool in fatigue testing applications. Counting is based on a search for specific events in the load-time function, e.g. a certain load level being exceeded or a load alternation of a certain amplitude. For this purpose, the range of values of the load-time function is divided into discrete intervals, or classes. Each event found is assigned to a class and counted in this class.
