Book Synopsis Viscoplasticité, endommagement, mécanique de la rupture et mécanique du contact by : FRANÇOIS
Download or read book Viscoplasticité, endommagement, mécanique de la rupture et mécanique du contact written by FRANÇOIS and published by Lavoisier. 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 Superplastic Flow written by K.A. Padmanabhan and published by Springer Science & Business Media. This book was released on 2001-02-26 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book aims at the following: - To outline briefly the techniques of mechanics of solids, particularly as it applies to strain rate sensitive materials, - to assess the present level of investigations on the mechanical behaviour of superplastics, - to formulate the main issues and challenges in mechanics of superplasticity, - to analyse the mathematical models/constitutive equations for superplastic flow from the viewpoint of mechanics, - to review the models of superplastic metal working processes, - to indicate with examples possible new results that can be obtained using the methods of mechanics of solids. It is intended for a variety of readers who may be interested in the phenomenon of superplasticity for different reasons: materials scientists and physicists working in educational institutions and R&D units, those who wish to work on the applications of superplasticity, engineers in industry, students at senior undergraduate and postgraduate levels and those who wish to understand the phenomenology and mechanics of superplasticity without involvement in actual research. A reader who has exposure to standard differential and integral calculus and elementary tensor calculus at a level taught to senior undergraduate students at a technical university should have no difficulty in following the treatments. The analytical procedures are explained in an Appendix with simple examples.

Book Synopsis Effect of Grain Size on Superplastic Deformation of Metallic Materials by : Jayaganthan Rengaswamy
Download or read book Effect of Grain Size on Superplastic Deformation of Metallic Materials written by Jayaganthan Rengaswamy and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The superplastic deformation exhibited by metals with different grain sizes and their corresponding deformation mechanism influences the industrial metal-forming processes. The coarse-grained materials, which contain grain size greater than 20¬†Œom, exhibited superplastic deformation at high homologous temperature and low strain rate of the order of 10,àí4¬†s,àí1. Fine grain materials (1,Äì20¬†Œom) are generally considered as favorable for superplastic deformation. They possess high-strain-rate sensitivity ,Äúm,Äù value, approximately, equal to 0.5 at the temperature of 0.5 times the melting point and at a strain rate of 10,àí3 to 10,àí4¬†s,àí1. Ultrafine grains (100¬†nm to less than 1¬†Œom) exhibit superplasticity at high strain rate as well as at low temperature when compared to fine grain materials. It is attributed to the fact that both temperature and strain rates are inversely proportional to the grain size in Arrhenius-type superplastic constitute equation. The superplastic phenomenon with nano-sized grains (10¬†nm to less than 100¬†nm) is quite different from their higher-scale counterparts. It exhibits high ductility with high strength. Materials with mixed grain size distribution (bimodal or layered) are found to exhibit superior superplasticity when compared to the homogeneous grain-sized material. The deformation mechanisms governing these superplastic deformations with different scale grain size microstructures are discussed in this chapter.
