Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage rassemble différentes contributions autour des problèmes de mécanique posés par les interfaces solide/solide. Que ce soit dans les matériaux traditionnels (alliages polyphasés, composites) ou dans les nouvelles technologies (couches minces, nano- et micro-dispositifs) les interfaces sont omniprésentes et conditionnent souvent le fonctionnement optimal de ces structures multi-constituées. Les différents aspects abordés ont pour objectif d'apporter les notions de base nécessaires à l'étude et à la compréhension des états de déformation et de contrainte au voisinage des interfaces dans les matériaux hétérogènes et leurs conséquences pratiques. Cet ouvrage s'adresse aux ingénieurs confrontés à des problèmes spécifiques dus aux effets d'hétérogénéités ainsi qu'aux chercheurs scientifiques abordant les problèmes fondamentaux liés à l'influence d'une interface sur le comportement mécanique d'un élément de matière hétérogène. Il pourra également être utile aux étudiants d'école d'ingénieur, de master et de doctorat en physique de la matière condensée ou en science et génie des matériaux.
Download or read book Grain Boundaries written by Louisette Priester and published by Springer Science & Business Media. This book was released on 2012-11-28 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain boundaries are a main feature of crystalline materials. They play a key role in determining the properties of materials, especially when grain size decreases and even more so with the current improvements of processing tools and methods that allow us to control various elements in a polycrystal. This book presents the theoretical basis of the study of grain boundaries and aims to open up new lines of research in this area. The treatment is light on mathematical approaches while emphasizing practical examples; the issues they raise are discussed with reference to theories. The general approach of the book has two main goals: to lead the reader from the concept of ‘ideal’ to ‘real’ grain boundaries; to depart from established knowledge and address the opportunities emerging through "grain boundary engineering", the control of morphological and crystallographic features that affect material properties. The book is divided in three parts: I ‘From interganular order to disorder’ deals with the concept of the perfect grain boundary, at equilibrium, and questions the maintenance of its crystalline state. II ‘From the ideal to the real grain boundary’ deals with the concept of the faulted grain boundary. It attempts to reveal the influence of the grain boundary structure on its defects, their formation and their accommodation. III ‘From free to constrained grain boundaries’ is devoted to grain boundary ensembles starting from the triple junction (the elemental configuration) to real grain boundary networks in polycrystals This part covers a new and topical development in the field. It presents for the first time an avenue for researchers working on macroscopic aspects, to approach the scale of description of grain boundaries. Audience: graduate students, researchers and engineers in Materials Science and all those scientists pursuing grain boundary engineering in order to improve materials performance.
Download or read book Grain Boundaries and Crystalline Plasticity written by Louisette Priester and published by John Wiley & Sons. This book was released on 2013-02-07 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of this book is to put forward the fundamental role of grain boundaries in the plasticity of crystalline materials. To understand this role requires a multi-scale approach to plasticity: starting from the atomic description of a grain boundary and its defects, moving on to the elemental interaction processes between dislocations and grain boundaries, and finally showing how the microscopic phenomena influence the macroscopic behaviors and constitutive laws. It involves bringing together physical, chemical and mechanical studies. The investigated properties are: deformation at low and high temperature, creep, fatigue and rupture.

Download or read book Perspectives in Creep Fracture written by M. F. Ashby and published by Elsevier. This book was released on 2014-05-23 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perspectives in Creep Fracture is a collection of studies that covers the advances in the analysis of the mechanisms involved in the process of creep fracture. The book presents nine articles that present data and discuss the theoretical advancement in the field. The text first covers the mechanisms leading to fracture in metals and ceramics, and then proceeds to tackling the problem of the nucleation of creep damage. Next, the book details the models for the growth of cracks and voids by diffusion and by plastic processes. The next two chapters deal with the creep fracture of ceramics. In the eighth chapters, the text examines the development and propagation of creep cracks. The last chapter details the theory involved in the propagation of cracks by cavitation. The book will be of great interest to researchers and practitioners of materials engineering, metallurgy, and other fields involved in fracture mechanics.

Book excerpt: Les avancées techniques requièrent une excellente maîtrise des matériaux utilisés. Le défi est de mieux comprendre leur comportement mécanique et plus particulièrement les relations entre leurs micro-structures et leurs propriétés à l'échelle macroscopique. Cet ouvrage apporte les éléments pour relever ce défi. Partant des mécanismes de déformation, il remonte aux lois de comportement macroscopique en cherchant à établir des relations quantitatives, en tout cas à révéler les phénomènes physiques qui sous-tendent les comportements rhéologiques. Les auteurs ont inclus les développements les plus récents, notamment sur les matériaux hétérogènes (alliages métalliques, polymères, composites). Chacun des chapitres est consacré à une grande classe de comportement : élastique puis plastique dans ce premier volume , comportement viscoélastique, comportement viscoplastique, endommagements, dans le second volume (on y trouvera en outre des notions de mécanique de la rupture et de mécanique du contact). Les outils de base (mécanique des milieux continus, cristallographie, changements de phase) sont décrits en annexes. On trouvera également, de nombreux exercices en fin de chapitres, pour la bonne compréhension des sujets traités. Une illustration abondante facilite la lecture de l'ouvrage. 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.
Download or read book Mechanical Behaviour of Materials written by Dominique François and published by Springer Science & Business Media. This book was released on 2012-12-24 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: Designing new structural materials, extending lifetimes and guarding against fracture in service are among the preoccupations of engineers, and to deal with these they need to have command of the mechanics of material behaviour. This ought to reflect in the training of students. In this respect, the first volume of this work deals with elastic, elastoplastic, elastoviscoplastic and viscoelastic behaviours; this second volume continues with fracture mechanics and damage, and with contact mechanics, friction and wear. As in Volume I, the treatment links the active mechanisms on the microscopic scale and the laws of macroscopic behaviour. Chapter I is an introduction to the various damage phenomena. Chapter II gives the essential of fracture mechanics. Chapter III is devoted to brittle fracture, chapter IV to ductile fracture and chapter V to the brittle-ductile transition. Chapter VI is a survey of fatigue damage. Chapter VII is devoted to hydrogen embrittlement and to environment assisted cracking, chapter VIII to creep damage. Chapter IX gives results of contact mechanics and a description of friction and wear mechanisms. Finally, chapter X treats damage in non metallic materials: ceramics, glass, concrete, polymers, wood and composites. The volume includes many explanatory diagrams and illustrations. A third volume will include exercises allowing deeper understanding of the subjects treated in the first two volumes.

This book was released on 2012-04-16 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les aciers inoxydables duplex sont des alliages Fe-Cr-Ni-Mo dont l'utilisation s'est fortement accrue depuis 10 ans. Leur structure biphasée leur assure une plus haute résistance mécanique et une plus haute résistance à la corrosion que n'ont les aciers inoxydables austénitiques standard. Ces nuances duplex ont un succès commercial continument croissant pour un large domaine d'applications (secteurs énergétiques, industries du gaz et du pétrole, industries chimiques, chimiquiers, industries du papier et de la pâte à papier…), dû à leurs très bonnes propriétés et leur relativement faible coût.

This book was released on 2009-04-07 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Modelling Small Deformations of Polycrystals written by J. Gittus and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific work of Jean Mandel has been exceptionally rich in the area of the mechanics of solids; the subjects which he has treated have been extremely diverse, from the theory of plasticity, buckling, soil mechanics, visco-elasticity, the theory of reduced models, and thermo dynamics, to percolation in porous media. But throughout this com prehensive work Jean Mandel has always maintained his interest in forming connections between the properties of materials (strength, deformability, viscosity) and the properties of their basic constituents. What is sometimes referred to in materials science as the transition from the microscopic to the macroscopic has for him been a very constant direction of research, which he never ceased to encourage in the Laboratoire de Mecanique des Solides of which he was the director. It is known that in the plasticity of metals permanent deformations must be sought in intercrystalline slip and more generally in disloca tions and the various microstructural defects. Before deformation of polycrystals is tackled, it is necessary to understand the mechanisms which take place within the crystal: the different systems of slip which may be activated and also the elementary mechanisms of twinning. Jean Mandel has shown how to make the transition from the behaviour of the single crystal to that of the polycrystal and has given the relation ships between the overall permanent deformation of the polycrystal and the plastic deformation of the single crystal.
