Ett Haighdiagram visar hur amplitud- respektive mittspänning ( respektive ) orsakar utmattning av materialet. I Haighdiagrammet ovan ses en röd linje som utgår från utmattningsgränsen som sedan följer sträckgränsen . Området under denna linje utsätts inte för utmattning. Utanför denna linje sker dock utmattningsbrott.
