Analyse mécanique par une méthode hybride du comportement d'un matériau revêtu sollicité en fretting

Abstract

The present note describes the process settled for analysis of coated contacts submitted either to a normal load or a tangential one. This hybrid method uses a Finite Element Method in addition to the experimental results. Effects of a soft coating and a hard layer are studied on elastic contact parameters (F.E.M.), and on the resistance to fretting fatigue (experimentation + F.E.M.). The use of Dang Van criterion allows us to determine the crack initiation threshold.
