CYCLE COUNTING FATIGUE DAMAGE
This paper describes a recently introduced counting method and presents comparisons between various fatigue-life predictions based on this and another common cycle-counting method. This new technique is known as the rainflow or Pagoda-Roof method. It is compared in this document with Range-Mean analysis which has been used extensively in recent years. An essential step in the prediction of the fatigue life of vehicles and structures is the reduction of a service strain or stress history to a series of cycles and half cycles (ranges). This process is known as cycle counting and can be the source of large but unnecessary errors in the subsequent life prediction.
