What is Thermal Fatigue?


Definitions are suggested for terms such as thermal fatigue, thermal-mechanical fatigue, and thermal-stress fatigue. Historical developments in the field of thermal fatigue from 1838 to the present are reviewed. It is hypothesized that we have advanced from qualitative to quantitative understanding of the thermal fatigue process and can now make life predictions with factor-of-two reliability for conventional metals.
