Numerical approach in thermomechanical fatigue

Résumé

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 constitutive law and of the damage and a failure criterion. This approach is applied on cylinder heads and on exhaust manifolds submitted to transient thermal loading and permits to predict the cracked area as well as the lifetime. The main hypothesis and the different aspects are detailed and results on automotive parts are presented.
