Numerical approach in thermomechanical fatigue

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

This paper presents a global approach of thermomechanical design in the automotive industry based on four different aspects ; the loading definition, the modelling of the c onssitutive law and of the damage and a failure criterion. This approach is applied on cylinder heads and on exhaust manifolds submitted to transsent thermal loading and permits to predict the cracked area as weH as the lifetime. The man hypothesss and the different aspect s are detailed and results on automotive parts are presented.
