Rainflow Counting

Rainflow counting er en metode for å telle utmattingssykluser som konverterer en kompleks spenningshistorikk til individuelle sykluser for skadevurdering. Utviklet av Tatsuo Endo og kolleger i 1974, gir den den mest fysisk realistiske representasjonen av utmattingsskade når den kombineres med Miners lineære kumulative skadehypotese. Algoritmen har blitt industristandarden innen pålitelighetsteknikk og vibrasjonsanalyse.
