Titre : An efficient 3D model of heterogeneous materials for elastic contact applications using multigrid methods Type de document : texte imprimé Auteurs : Hugo Boffy, Auteur ; Marie-Christine Baietto, Auteur ; Philippe Sainsot, Auteur Année de publication : 2012 Article en page(s) : 08 p. Note générale : tribology Langues : Anglais (eng) Mots-clés : 3D graded coating/substrate model  homogeneous material  three-dimensional examples Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : A 3D graded coating/substrate model based on multigrid techniques within a finite difference frame work is presented. Localized refinement is implemented to optimize memory requirement and computing time. Validation of the solver is performed through a comparison with analytical results for (i) a homogeneous material and (ii) a graded material. The algorithm performance is analyzed through a parametric study describing the influence of layer thickness (0.01 DEWEY : 621.5 ISSN : 0742-4787 En ligne : http://asmedl.org/getabs/servlet/GetabsServlet?prog=normal&id=JOTRE9000134000002 [...] [article] An efficient 3D model of heterogeneous materials for elastic contact applications using multigrid methods [texte imprimé] / Hugo Boffy, Auteur ; Marie-Christine Baietto, Auteur ; Philippe Sainsot, Auteur . - 2012 . - 08 p. tribology Langues : Anglais (eng) in Transactions of the ASME .
