Available in PDF, EPUB and Kindle. Book excerpt: A L'HEURE ACTUELLE, IL N'EXISTE AUCUNE THEORIE CAPABLE D'ASSURER LE PASSAGE ENTRE LA THEORIE DES DISLOCATIONS ET LE FORMALISME DE LA MECANIQUE DES MILIEUX CONTINUS. LE PRESENT TRAVAIL TIRE PARTI DU DEVELOPPEMENT D'UNE SIMULATION DE LA DYNAMIQUE DES DISLOCATIONS A L'ECHELLE DE LA MICROSTRUCTURE (DEVELOPPEE AU LEM), POUR REALISER UN COUPLAGE AVEC UN CODE ELEMENTS FINIS (ZEBULON DEVELOPPE PAR L'ONERA ET L'ENSMP). LE CODE HYBRIDE 3-D AINSI REALISE OU MODELE DISCRET-CONTINU PERMET, POUR LA PREMIERE FOIS, D'INCORPORER LES PROPRIETES PHYSIQUES DES DEFAUTS ET LES LONGUEURS D'ECHELLE QUI LEUR SONT ASSOCIEES TOUT EN PERMETTANT UN TRAITEMENT RIGOUREUX DES CONDITIONS AUX LIMITES. AU COURS DE CE TRAVAIL, UNE QUESTION FONDAMENTALE, CELLE DE L'HOMOGENEISATION DE LA DEFORMATION PLASTIQUE A DU ETRE ABORDEE. AINSI, UN FORMALISME D'ECHANGE DE DONNEES ENTRE MODELISATIONS A L'ECHELLE MICROSCOPIQUE ET A L'ECHELLE MACROSCOPIQUE A PU ETRE DEFINI. APRES UNE ETAPE DE VALIDATION SUR DES CONFIGURATIONS MODELES DE DISLOCATIONS, DES CALCULS ONT ETE EFFECTUES SUR DES PROBLEMES LIES A LA DEFORMATION PLASTIQUE EN MILIEU CONFINE. LE MOUVEMENT DES DISLOCATIONS ET LES CONTRAINTES CRITIQUES CORRESPONDANTES ONT ETE SIMULES DANS DES COUCHES MINCES OU DES CANAUX, EN TENANT COMPTE DE DIFFERENTES SOURCES DE CONTRAINTES INTERNES COMME LES CONTRAINTES D'ECART PARAMETRIQUE ET LES CONTRAINTES D'INCOMPATIBILITE ELASTIQUE. CETTE SIMULATION HYBRIDE SERA ETENDUE DANS UN PROCHE AVENIR A DES MICROSTRUCTURES PLUS COMPLEXES COMME CELLES DE MATERIAUX CONTENANT DES INTERFACES OU INTERPHASES INTERNES ET/OU SOUMISES A DES CHARGEMENTS COMPLEXES.

Download or read book Non Linear Mechanics of Materials written by Jacques Besson and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: In mechanical engineering and structural analysis there is a significant gap between the material models currently used by engineers for industry applications and those already available in research laboratories. This is especially apparent with the huge progress of computational possibilities and the corresponding dissemination of numerical tools in engineering practice, which essentially deliver linear solutions. Future improvements of design and life assessment methods necessarily involve non-linear solutions for inelastic responses, in plasticity or viscoplasticity, as well as damage and fracture analyses. The dissemination of knowledge can be improved by software developments, data base completion and generalization, but also by information and training. With such a perspective Non-Linear Mechanics of Materials proposes a knowledge actualization, in order to better understand and use recent material constitutive and damage modeling methods in the context of structural analysis or multiscale material microstructure computations.

Download or read book Configurational Forces written by Gerard A. Maugin and published by CRC Press. This book was released on 2016-04-19 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring recent developments in continuum mechanics, Configurational Forces: Thermomechanics, Physics, Mathematics, and Numerics presents the general framework for configurational forces. It also covers a range of applications in engineering and condensed matter physics. The author presents the fundamentals of accepted standard continuum mechanics, before introducing Eshelby material stress, field theory, variational formulations, Noether’s theorem, and the resulting conservation laws. In the chapter on complex continua, he compares the classical perspective of B.D. Coleman and W. Noll with the viewpoint linked to abstract field theory. He then describes the important notion of local structural rearrangement and its relationship to Eshelby stress. After looking at the relevance of Eshelby stress in the thermodynamic description of singular interfaces, the text focuses on fracture problems, microstructured media, systems with mass exchanges, and electromagnetic deformable media. The concluding chapters discuss the exploitation of the canonical conservation law of momentum in nonlinear wave propagation, the application of canonical-momentum conservation law and material force in numerical schemes, and similarities of fluid mechanics and aerodynamics. Written by a long-time researcher in mechanical engineering, this book provides a detailed treatment of the theory of configurational forces—one of the latest and most fruitful advances in macroscopic field theories. Through many applications, it shows the depth and efficiency of this theory.
Download or read book Th orie eul rienne des milieux d formables written by Gérard Gremaud and published by EPFL Press. This book was released on 2013-09-24 with total page 778 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage propose une théorie unifiée, originale et novatrice de la déformation des milieux fluides et solides. Les équations fondamentales d’évolution des milieux déformables y sont développées de façon méthodique et rigoureuse, sous forme vectorielle et en coordonnées d’Euler. Elles sont appliquées à la description phénoménologique des fluides viscoélastiques, des fluides chimiques, des solides élastiques, des solides auto-diffusifs, des solutions solides et des solides anélastiques et plastiques. L’introduction dans les équations d’évolution du concept de charges tensorielles de dislocation et de désinclinaison permet une approche rigoureuse de l’anélasticité et de la plasticité des solides, via l’évolution des singularités topologiques qu’ils contiennent.

This book was released on 2017-08-16 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage propose une présentation de la mécanique des milieux continus destinée aux élèves des écoles d’ingénieurs et des formations universitaires (L3 et M1). Chaque chapitre comporte un exposé synthétique des concepts qui est ensuite illustré et complété sous forme d’exercices corrigés. L’initiation au calcul tensoriel qui occupe les premières pages de cet ouvrage est rapidement mise à profit dans le cadre de la description mathématique de la transformation géométrique et de la représentation des efforts intérieurs. On traite les deux points de vue lagrangien et eulérien. Les concepts de contrainte et de déformation sont d’abord mis en oeuvre à l’occasion d’une brève introduction au calcul à la rupture. La théorie de l’élasticité est essentiellement présentée et illustrée dans le cas de la linéarité, mais une initiation à l’élasticité en transformation finie est proposée en exercices. On détaille d’abord les méthodes de résolution directe basées sur des potentiels en déplacement ou en contrainte. Ensuite, une place importante est réservée aux méthodes variationnelles. En particulier, la méthode des éléments finis est illustrée dans le cadre de plusieurs exercices. L’ouvrage propose également une introduction à la mécanique des fluides. L’attention est dirigée principalement vers l’étude des écoulements potentiels. Celle-ci est complétée par une prise de contact avec la notion de couche limite en raison de l’interconnexion de ces deux modélisations. L’étude des milieux curvilignes élastiques clôture cet ouvrage.

Available in PDF, EPUB and Kindle. Book excerpt: Inverse Problems in the Mechanics of Materials concentrates on two timely subjects: Ill-posed inverse problems related to defect identification; and the mechanics of homogeneous and heterogeneous media, including such topics as cracked bodies, solids with interfaces or inclusions, and materials rendered inhomogeneous by irreversible deformation due to their thermomechanical history. These intriguing subjects are not found together in previous publications. Written in a unique, easy-to-read format, Inverse Problems in the Mechanics of Materials provides quick access to current information. It includes up-to-date references and many recent results, particularly in such classical subjects as elasticity, plasticity, and fracture mechanics. The reader discovers numerous recipes for solving inverse problems, and reviews of available methods provide applications to real-life problems in industry.
