Counting rainflow

The counting rainflow is used in analysis of tiredness with an aim of reducing the spectrum of Contrainte S in a series of simple constraints.

Its importance is due to the fact that it allows the application of the rule To undermine to predict the lifespan of a structure subjected to complex loads. The algorithm was developed by Tatsuo Endo and Mr. Matsuiski in 1968. Although there exist many methods of counting for this type of applications, counting rainflow today is used.
