Book Synopsis Analyse variationnelle de quelques problemes viscoélastiques et viscoplastiques avec frottement by : Bassam Awbi
Download or read book Analyse variationnelle de quelques problemes viscoélastiques et viscoplastiques avec frottement written by Bassam Awbi and published by . This book was released on 2001 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur l'étude de quelques problèmes aux limites de contact avec frottement entre un corps déformable et une fondation. Nous considérons des lois de comportement non linéaires et des processus quasistatiques. Les résultats que nous obtenons concernent l'existence et l'unicité des solutions faibles et la dépendance continue par rapport aux données. La thèse est composée de quatre chapitres. Dans le premier chapitre nous présentons les divers modèles mécaniques de contact étudiés et nous rappelons quelques outils d'analyse fonctionnelle. Le deuxième chapitre est destiné à l'étude des problèmes quasistatiques pour des matériaux viscoplastiques de Kelvin-Voigt. Nous y étudions un problème de contact bilatéral avec frottement de Coulomb régularisé, ainsi qu'un problème de contact modélisé à l'aide d'une loi générale de réponse normale instantanée avec frottement décrit par une loi locale sans seuil. Dans le troisième chapitre on traite les problèmes mécaniques précédents dans un cadre fonctionnel abstrait afin d'avoir une vision globale des résultats obtenus dans le deuxième chapitre. Finalement dans le quatrième chapitre on considère deux modèles mathématiques qui décrivent l'écoulement du fluide de Bingham, avec des conditions aux limites de contact avec frottement.

ON ETUDIE AUSSI QUELQUES PROPRIETES DE LA SOLUTION TELLES QUE LE LIEN ENTRE LES SOLUTIONS DES DEUX FORMULATIONS VARIATIONNELLES AINSI QUE LA DEPENDANCE CONTINUE DE LA SOLUTION PAR RAPPORT AUX DONNEES ET AUX PARAMETRES. POUR LE PROBLEME PARFAITEMENT PLASTIQUE, ON OBTIENT DEUX RESULTATS D'EXISTENCE ET D'UNICITE MOYENNANT UNE METHODE DE REGULARISATION. POUR CONCLURE ON INTRODUIT UN FORMALISME GENERAL QUI PERMET DE RESOUDRE D'AUTRES PROBLEMES DU MEME TYPE. ON ETUDIE DEUX INCLUSIONS DIFFERENTILLES ET DEUX SYSTEMES DIFFERENTIELS POUR GENERALISER LA THEORIE INTRODUITE AUPARAVANT.

Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL EST UNE CONTRIBUTION A L'ETUDE DE PROBLEMES BIDIMENSIONNELS DE CONTACT AVEC FROTTEMENT, ENTRE UN CORPS RIGIDE ET UN SOLIDE DEFORMABLE ELASTOPLASTIQUE, EN PRESENCE DE GRANDES DEFORMATIONS ET DE GRANDS DEPLACEMENTS. PLUS PRECISEMENT, ON S'INTERESSE A L'INFLUENCE DU FROTTEMENT ET A L'INFLUENCE DE LA PRESENCE DES JONCS DE RETENUE SUR LE ROLE DU SERRE-FLAN EN EMBOUTISSAGE. LE COMPORTEMENT VOLUMIQUE DU MATERIAU EST SUPPOSE ELASTOPLASTIQUE ISOTROPE, AVEC ECROUISSAGE ISOTROPE. LE MODELE RETENU UTILISE LA NOTION DE CONFIGURATION INTERMEDIAIRE OBTENUE PAR DECHARGE ELASTIQUE LOCALE DU MATERIAU. LE COMPORTEMENT ENTRE LA CONFIGURATION INTERMEDIAIRE ET LA CONFIGURATION ACTUELLE EST CARACTERISE PAR UNE REPONSE HYPERELASTIQUE. LA CONFIGURATION INTERMEDIAIRE EST ACTUALISEE PAR INTEGRATION DES LOIS D'EVOLUTION PLASTIQUE, EN UTILISANT UNE METHODE DE PREDICTION ELASTIQUE-CORRECTION PLASTIQUE (PAR RETOUR RADIAL). UN TRAITEMENT PARTICULIER DU CARACTERE INCOMPRESSIBLE DE LA PLASTICITE, BASE SUR UNE FORMULATION A TROIS CHAMPS, EST PROPOSE. LE COMPORTEMENT SURFACIQUE EST DECRIT PAR DES CONDITIONS DE CONTACT UNILATERAL AVEC FROTTEMENT DE COULOMB. LA FORMULATION CONTINUE EN GRANDES DEFORMATIONS EST ABORDEE. LA RESOLUTION DES EQUATIONS D'EQUILIBRE NON-LINEAIRES AVEC CONTRAINTES (DUES AU CONTACT ET AU FROTTEMENT) NECESSITE L'UTILISATION D'UNE METHODE DE NEWTON GENERALISEE. DIFFERENTES METHODES NUMERIQUES POUR RESOUDRE, A CHAQUE ITERATION D'EQUILIBRE, LE SYSTEME LINEAIRE AVEC CONTRAINTES SONT PRESENTEES ET COMPAREES: METHODES DE PROGRAMMATION MATHEMATIQUE (LEMKE, GAUSS-SEIDEL, ROSEN), TECHNIQUES DE REGULARISATION (PENALISATION, LAGRANGIEN AUGMENTE). UN ALGORITHME DE PILOTAGE EN DEPLACEMENT PERMETTANT DE MAINTENIR L'EFFORT APPLIQUE PAR LE SERRE-FLAN EST PROPOSE. DES RESULTATS D'ETUDES NUMERIQUES ET EXPERIMENTALES SUR L'INFLUENCE DU FROTTEMENT SUR LES PETITS RAYONS SONT PRESENTES ET COMPARES. ENFIN UN PROBLEME D'EMBOUTISSAGE COMPLET EST TRAITE

Book Synopsis Cyclic Plasticity of Metals by : Hamid Jahed
Download or read book Cyclic Plasticity of Metals written by Hamid Jahed and published by Elsevier. This book was released on 2021-11-11 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclic Plasticity of Metals: Modeling Fundamentals and Applications provides an exhaustive overview of the fundamentals and applications of various cyclic plasticity models including forming and spring back, notch analysis, fatigue life prediction, and more. Covering metals with an array of different structures, such as hexagonal close packed (HCP), face centered cubic (FCC), and body centered cubic (BCC), the book starts with an introduction to experimental macroscopic and microscopic observations of cyclic plasticity and then segues into a discussion of the fundamentals of the different cyclic plasticity models, covering topics such as kinematics, stress and strain tensors, elasticity, plastic flow rule, and an array of other concepts. A review of the available models follows, and the book concludes with chapters covering finite element implementation and industrial applications of the various models. - Reviews constitutive cyclic plasticity models for various metals and alloys with different cell structures (cubic, hexagonal, and more), allowing for more accurate evaluation of a component's performance under loading - Provides real-world industrial context by demonstrating applications of cyclic plasticity models in the analysis of engineering components - Overview of latest models allows researchers to extend available models or develop new ones for analysis of an array of metals under more complex loading conditions
Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.
