Concevoir de nouveaux matériaux de structure, allonger la durée de vie des pièces, éviter les ruptures en service font partie des préoccupations majeures des ingénieurs. Une bonne maîtrise du comportement mécanique des matériaux est essentielle pour aboutir à ce résultat. Cet ouvrage aborde ce sujet dans les domaines de la viscoplasticité, de l'endommagement, de la résistance à la fissuration et de la mécanique du contact. Faisant suite à un précédent volume sur le comportement mécanique des matériaux, consacré à l'élasticité et à l'élastoplasticité, il conserve la même démarche qui consiste, en partant des mécanismes actifs à l'échelle microscopique, à remonter aux lois macroscopiques. Le premier chapitre concerne les comportements viscoplastiques qui se manifestent, par exemple, à basse température, par une influence de la vitesse de sollicitation, ou, à haute température, par le fluage sous charge constante. Le deuxième chapitre traite des très nombreux phénomènes d'endommagement que l'on rencontre dans tous les matériaux (métalliques, polymères, verres, bétons ...), comme la cavitation, la fatigue, la corrosion sous contrainte. Le troisième chapitre donne les notions de mécanique de la rupture nécessaires pour comprendre la résistance de la fissuration. Le quatrième chapitre apporte les notions principales de mécanique du contact. Chaque chapitre est suivi d'exercices, énoncés de telle sorte que le lecteur est guidé pas à pas pour trouver la solution. De très nombreuses illustrations facilitent la lecture. Comportement mécanique des matériaux est le fruit du DEA "Mécanique et Matériaux" de la région parisienne. Il s'adresse aussi aux élèves-ingénieurs, ingénieurs et chercheurs. Les développements mathématiques y sont d'un accès facile. Les réelles difficultés, dont la maîtrise n'est pas exempte d'aspects passionnants, résident dans les fréquents changements d'échelle et dans le sens physique auquel il est fait appel.

Three subjects of major interest in one textbook: linear elasticity, mechanics of structures in linear isotropic elasticity, and nonlinear mechanics including computational algorithms. After the simplest possible, intuitive approach there follows the mathematical formulation and analysis, with computational methods occupying a good portion of the book. There are several worked-out problems in each chapter and additional exercises at the end of the book, plus mathematical expressions are bery often given in more than one notation. The book is intended primarily for students and practising engineers in mechanical and civil engineering, although students and experts from applied mathematics, materials science and other related fields will also find it useful.

This book offers a recipe for constructing the numerical models for representing the complex nonlinear behavior of structures and their components, represented as deformable solid bodies. Its appeal extends to those interested in linear problems of mechanics.

Advances in technology are demanding ever-increasing mastery over the materials being used: the challenge is to gain a better understanding of their behaviour, and more particularly of the relations between their microstructure and their macroscopic properties. This work, of which this is the first volume, aims to provide the means by which this challenge may be met. Starting from the mechanics of deformation, it develops the laws governing macroscopic behaviour – expressed as the constitutive equations – always taking account of the physical phenomena which underlie rheological behaviour. The most recent developments are presented, in particular those concerning heterogeneous materials such as metallic alloys, polymers and composites. Each chapter is devoted to one of the major classes of material behaviour. As the subtitles indicate, Volume 1 deals with micro- and macroscopic constitutive behaviour and Volume 2 with damage and fracture mechanics. A third volume will be devoted to exercises and their full solutions complementing the content of these two first volumes. Most of the chapters end with a set of exercises, to many of which either the full solution or hints on how to obtain this are given; each volume is profusely illustrated with explanatory diagrams and with electron-microscope photographs. This book, now in its second edition, has been rigorously re-written, updated and modernised for a new generation. The authors improved the existing material, in particular in modifying the organisation, and added new up-to-date content. Understanding the subject matter requires a good knowledge of solid mechanics and materials science; the main elements of these fields are given in a set of annexes at the end of the first volume. The authors also thought it interesting for the readers to give as footnotes some information about the many scientists whose names are attached to theories and formulae and whose memories must be celebrated. Whilst the present book, as well as Volume 2, is addressed primarily to graduate students, part of it can be used in undergraduate courses; and it is hoped that practising engineers and scientists will find the information it conveys useful. It is the authors’ hope also that English-speaking readers will want to learn about the aspects of French culture, and more particularly of the French school of micromechanics of materials, which this treatment undoubtedly displays.

This book presents a novel approach to the classical scientific discipline of Structural Engineering, which is inspired by numerous current applications from domains of Civil, Mechanical or Aerospace Engineering. The main goal of this book is to help with making the best choice between accuracy and efficiency, when it comes to building the most suitable structural models by practising engineers using modern computational tools available in commercial software products (SAP, FEAP, ANSYS ...) for which we have carried out many developments that have been become the main reference in the field. Any development of this kind is not a mere modification of discrete approximation, but a thorough treatment with a sound theoretical formulation based upon Hu-Washizu variational principle with independent rotation field, its corresponding regularization and finally the most appropriate finite element interpolation that can match those used for structural elements. Proposed approach allows us to provide a unified discrete approximation of complex structural assemblies and greatly simplify the modeling task for structural engineers. Thus, in conclusion, this book can also be perceived as the theoretical manual for using modern computer models successfully by practising engineers.

This collection presents an exchange of ideas among scientists and engineers about the economic and safety concerns surrounding environmentally induced materials problems which lead to nuclear power plant outages. Scientists and engineers concerned with the environmental degradation processes (corrosion, mechanical, and radiation effects) present their latest results on such topics as life extension/relicensing and materials problems associated with spent fuel storage and radioactive waste disposal. This collection will be of interest to utility engineers, reactor vendor engineers, plant architect engineers, researchers concerned with materials degradation, and consultants involved in design, construction, and operation of water reactors.

L'objet de la veille anticipative, pour les entreprises et les collectivités, est la gestion de l'information de leur environnement extérieur afin d'anticiper les changements importants actuels et futurs pour leur devenir. Cet ouvrage synthétise l'état des recherches sur la veille anticipative et met en évidence leurs limites. Il expose les problématiques auxquelles les entreprises et les collectivités sont confrontées dans leurs démarches de veille et apporte les éléments théoriques et méthodologiques pour aider les praticiens dans leur réflexion sur la mise en place, l'optimisation et l'évaluation de leurs pratiques. Construit comme un dialogue entre la pratique et la théorie, ce livre permet de s'approprier de façon concrète les concepts théoriques et les méthodologies de veille et s'interroge sur de nouveaux axes de recherche.
