Abstract

Abstract:

The MansonCoffin equation, ostergren model and three-parameter power function for low cycle fatigue(LCF) are investigated, and a threeparameter strain energy function is developed for high temperature low cycle fatigue. The new method is validated by using a high temperature superalloy at 900 ℃.

Key words: low , cycle , fatigue, , life, , prediction
