Book excerpt: L'étude est limitée aux problèmes plans de contact engendres par de petites déformations élastiques des solides, sous l'effet de sollicitations statiques ou quasi-statiques (équations de l'élasticité linéaire). On traite divers critères de contact: adhérence, glissement parfait, frottement de coulomb. On expose les différentes approches numériques par éléments finis. Puis on propose une méthode d'éléments finis, utilisant les déplacements comme variables nodales, et basée sur la création d'un matériau fictif dit "matériau de contact". On traite des exemples numériques

Book Synopsis Method of Dimensionality Reduction in Contact Mechanics and Friction by : Valentin L. Popov
Download or read book Method of Dimensionality Reduction in Contact Mechanics and Friction written by Valentin L. Popov and published by Springer. This book was released on 2014-08-19 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes for the first time a simulation method for the fast calculation of contact properties and friction between rough surfaces in a complete form. In contrast to existing simulation methods, the method of dimensionality reduction (MDR) is based on the exact mapping of various types of three-dimensional contact problems onto contacts of one-dimensional foundations. Within the confines of MDR, not only are three dimensional systems reduced to one-dimensional, but also the resulting degrees of freedom are independent from another. Therefore, MDR results in an enormous reduction of the development time for the numerical implementation of contact problems as well as the direct computation time and can ultimately assume a similar role in tribology as FEM has in structure mechanics or CFD methods, in hydrodynamics. Furthermore, it substantially simplifies analytical calculation and presents a sort of “pocket book edition” of the entirety contact mechanics. Measurements of the rheology of bodies in contact as well as their surface topography and adhesive properties are the inputs of the calculations. In particular, it is possible to capture the entire dynamics of a system – beginning with the macroscopic, dynamic contact calculation all the way down to the influence of roughness – in a single numerical simulation model. Accordingly, MDR allows for the unification of the methods of solving contact problems on different scales. The goals of this book are on the one hand, to prove the applicability and reliability of the method and on the other hand, to explain its extremely simple application to those interested.

Book Synopsis Amélioration de la modélisation de contact pour les procédés à faible zone de contact by : Maha Hachani
Download or read book Amélioration de la modélisation de contact pour les procédés à faible zone de contact written by Maha Hachani and published by . This book was released on 2011 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail vise Ce travail vise à améliorer la performance du code éléments finis FORGE®. En effet, la modélisation du contact dans ce code s'avère insatisfaisante pour simuler les procédés de mise en forme des matériaux à faible zone de contact. On présente dans ce mémoire les développements qui ont été réalisés pour améliorer le modèle de contact existant. Dans la première partie, partant de ce modèle, on s'intéresse à un problème spécifique qui est le procédé de laminage circulaire. Un nouveau modèle de traitement du contact dédié à ce procédé est développé. Il repose sur un schéma de réactualisation temporelle en coordonnées cylindriques, une formulation implicite et une description analytique des obstacles. La condition de contact incrémentale est alors imposée exactement en fin d'incrément. On valide ces développements sur plusieurs cas de procédé de laminage circulaire où l'on montre l'apport du nouvel algorithme en terme de précision de gestion de contact et aussi en terme d'amélioration des résultats de simulation et des temps de calcul. Dans la deuxième partie, on a généralisé cette approche à l'ensemble des procédés à faible zone pour lesquels une représentation analytique des outils n'est pas possible. On a développé alors un modèle implicite général basé sur la réactualisation de la condition de contact au cours des itérations de Newton-Raphson. Cette méthode permet de tenir compte exactement de l'évolution de la position relative de la pièce et de l'outil. Ensuite, on généralise le lissage des outils à des pièces de géométrie plus complexes. On étudie alors l'influence de la discrétisation de l'outil sur la précision de la simulation des procédés de mise en forme et particulièrement pour des procédés à faible zone de contact. Une méthode d'interpolation quadratique proposée par Nagata est alors implémentée pour le lissage de la surface des outils discrétisés par des éléments plans. La nouvelle surface interpolée est déterminée d'une façon locale à partir seulement de la position des nœuds et des normales nodales. Ces normales sont calculées à partir des normales aux facettes entourant le nœud considéré en utilisant la méthode des normales votées. L'efficacité de cette méthode combinée à schéma d'intégration implicite est testée pour plusieurs procédés de mise en forme.

L'ESSAI EST EFFECTUE DANS DES CONDITIONS OPTIMALES POUR SIMULER LA PRESSION DE CONTACT, LA DEFORMATION PLASTIQUE ET LA TEMPERATURE CARACTERISTIQUE DU PROCEDE DE MISE EN FORME. UNE ETAPE DE VALIDATION BASEE SUR UN CAS DE TREFILAGE MONTRE QUE LE COEFFICIENT DE FROTTEMENT ISSU DE L'ESSAI DE COMPRESSION-TRANSLATION EST PARFAITEMENT UTILISABLE POUR LA SIMULATION ELEMENTS FINIS DU PROCEDE. LA METHODOLOGIE D'ANALYSE EST ENSUITE UTILISEE POUR CARACTERISER LE COMPORTEMENT TRIBOLOGIQUE DES HUILES DE FRAPPE A FROID A PARTIR DE QUATRE CRITERES DE SELECTION : LE COEFFICIENT DE FROTTEMENT, LA LONGUEUR DE FROTTEMENT AVANT APPARITION DE RAYURES ET DE FISSURES, ET LA RUGOSITE RESULTANTE. UNE DERNIERE PHASE DE DEVELOPPEMENT PERMET DE REALISER DES ESSAIS CONSECUTIFS POUR REPRODUIRE LES SOLLICITATIONS DE LA SURFACE DU LOPIN SOUMISE A DES OPERATIONS DE MISE EN FORME SUCCESSIVES. LES RESULTATS DECRIVENT L'EVOLUTION DU FROTTEMENT EN FONCTION DES REVETEMENTS, DE LEUR DEGRADATION ET DES LUBRIFIANTS ADDITIONNELS.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.
