Rainflowmethode
The rainflow method is a widely used technique in fatigue analysis for counting and characterizing cycle loads in a fluctuating stress or strain history. Developed by the American researcher Nigel E. Dowling in the 1970s, it provides a systematic approach to decompose complex load time histories into simple, individual load cycles, which are essential for predicting material fatigue life.
This method visualizes stress or strain data as a closed hysteresis loop array, allowing engineers to identify
The rainflow counting procedure is favored because it accurately captures the effects of load reversals and
This technique is extensively employed in fields such as aerospace, automotive, civil engineering, and materials science,
