Public ISBD [article]  inTransactions of the ASME . Journal of tribology > Vol. 130 N° 4 (Octobre 2008) . - 9 p. Titre : Influence of crystallographic orientation on energy dissipation during sliding Type de document : texte imprimé Auteurs : Jeremy J. Dawkins, Auteur ; Richard W. Neu, Auteur Année de publication : 2015 Article en page(s) : 9 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Plasticity Deformation Crystals Energy dissipation Engineering simulation Cylinders Stress Friction Mechanisms Modeling Résumé : The aim of this study is to evaluate a methodology for modeling the influence of crystallographic grain orientation in sliding contacts. The simulations of translating interfering cylindrical asperities, using finite element analysis, were conducted using two different plasticity models for copper: a conventional isotropic, homogeneous J2 plasticity model and a continuum crystal plasticity model. Using crystal plasticity, the dependence of crystallographic orientation on plastic deformation and energy dissipation can be determined. The relative trends predicted using crystal plasticity are consistent with experiments that show friction depends on crystallographic orientation when plastic deformation is one of the primary energy dissipation mechanisms.
