Abstract. Afin d'évaluer le frottement à l'interface, on a étudié comparativement les contacts sphère – plan et galet – plan, pour la même distribution des contraintes de contact.
Les essais expérimentaux ont donné une bonne validation qualitative du modèle analytique proposée pour le microglissement à l'interface d'un contact élastique en roulement.
 

 

Keywords: microglissement, frottement en roulement, surface de contact
