This book was released on 2009 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le développement de nouveaux matériaux nécessite la détermination de leurs propriétés mécaniques aux échelles macro, micro et nanométrique. Parmi les méthodes expérimentales les plus courantes, l’essai d’indentation instrumentée permettant de déterminer le module d’élasticité et la dureté du matériau à toutes ces échelles de mesure est sans doute le plus utilisé. Cependant, les valeurs obtenues en micro et en nanoindentation sont souvent en apparente contradiction. Cela a conduit de nombreux auteurs à s’interroger sur la validité des mesures expérimentales, sur l’identification des processus physiques mis en jeu lors de l’enfoncement de l’indenteur ou encore sur la pertinence des propriétés mesurées et des échelles de mesure. Sans prétendre étudier tous les aspects de manière exhaustive ce problème complexe, nous proposons cependant quelques pistes de réflexions en particulier sur le passage nano/micro en dureté. Sur la base de la théorie du gradient de plasticité développé par Nix et Gao, nous définissons un facteur d’échelle qui relie certaines données expérimentales à des propriétés fondamentales du matériau. Nous montrons également que ce facteur d’échelle, capable de caractériser la résistance à la déformation plastique, peut donner des informations complémentaires pour étudier le comportement des matériau soumis à différentes conditions d’indentation. Dans une deuxième partie, nous étudions le fluage par indentation comme une alternative aux essais classiques de fluage qui durent généralement plusieurs mois. Même si le résultat ne répond pas complètement aux objectifs fixés, nous montrons qu’un modèle rhéologique adapté permet de retrouver le module d’élasticité et de calculer un coefficient de viscosité à température ambiante du matériau.

Download or read book propriétés mécaniques de friction et de déformation des surfaces de polymères solides written by Sébastien Lafaye and published by . This book was released on 2002 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le déplacement d'une pointe rigide sur la surface d'un polymère peut générer un glissement élastique ou une rayure plastique selon les conditions d'essais. La rayure de surfaces de polymères est accompagnée d'un relâchement élastique qui recouvre une partie du contact dorsal. Ce retour, dû à l'élasticité de ces matériaux, dépend du taux de plasticité dans le contact, et devient quasi symétrique lorsque le contact est glissant.Un dispositif d'essai de glissement-rayure développé au laboratoire permet de mesurer le frottement apparent lors du déplacement de la pointe, tout en ayant l'échantillon placé dans une enceinte thermique. Un dispositif de vision in-situ permet d'analyser l'aire réelle de contact entre la pointe rigide et la surface de l'échantillon. Le frottement apparent comporte une part de frottement vrai et une part d'obstacle due à l'écoulement viscoélastique et/ou viscoplastique de la matière. L'évaluation du frottement vrai local se fait à partir du frottement apparent et de la géométrie de contact accessible grâce à la vision in-situ, par un modèle de lignes de glissement autour de la pointe rigide qui permet de s'affranchir de la part déformation du frottement apparent.L'évolution du frottement vrai en fonction du taux de plasticité (nature de la réponse du contact) a montré que le passage entre un contact élastique et élastoplastique est accompagné d'un saut de frottement que l'on attribue à l'hystérésis d'adhésion.

Available in PDF, EPUB and Kindle. Book excerpt: Mise au point d'un dispositif qui permet de faire des mesures directes de tous les paramètres nécessaires pour déterminer les lois de comportement des sols, notamment du module d'Young, du coefficient de poisson et du coefficient d'amortissement. Il s'agit d'un essai triaxial cyclique a contrainte déviatoire cyclique imposée. a partir de la relation d'élasticité de hertz on propose des formules pour déterminer le module d'Young maximal a partir de trois paramètres: nature du sol, compacité et contrainte effective isotrope appliquée. Mise en évidence de la forte non linéarité du sol vis a vis de la composante déviatoire de la contrainte. On montre qu'une loi elasto-plastique basée sur le modèle de ramberg-osgood représente bien l'évolution du module et de l'amortissement en fonction de l'amplitude de déformation cyclique

Download or read book Inelastic Behaviour of Structures under Variable Loads written by Zenon Mróz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers is a state of the art presentation of theories and methods related to the problem of the behaviour of mechanical structures under variable loads beyond their elastic limit In particular, the problems of shakedown, ratchetting, transient and asymptotic cyclic states are addressed. The volume is composed of four chapters devoted to material modelling for cyclic loading conditions; general theory of accommodated states of structures; effects of changes of the geometry on the inelastic structural response; and numerical techniques with applications to particular engineering problems. It was aimed to provide a unified approach in order to understand both inelastic material and structural response under variable loading conditions. The attempt to extend the classical shakedown theory of Melan and Koiter to geometrically non-linear problems is presented in several papers. The industrial application of cyclic plasticity to the analysis and the design of pressure bellows, compensators, turbine disks, or flange connections under thermal and pressure cycles illustrates the great potential of the numerical techniques developed for this purpose using mostly min-max approaches. The treatment of railway problems and the analysis and optimisation of pavements are further examples of important areas of applications. Emphasis was laid on approaches that take into account the fact that loading histories are often not precisely known Therefore, the center of interest lies in other than step by step calculation methods.

Download or read book Inelastic Analysis of Structures under Variable Loads written by Dieter Weichert and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question whether a structure or a machine component can carry the applied loads, and with which margin of safety, or whether it will become unserviceable due to collapse or excessive inelastic deformations, has always been a major concern for civil and mechanical engineers. The development of methods to answer this technologically crucial question without analysing the evolution of the system under varying loads, has a long tradition that can be traced back even to the times of emerging mechanical sciences in the early 17th century. However, the scientific foundations of the theories underlying these methods, nowadays frequently called "direct", were established sporadically in the Thirties of the 20th century and systematically and rigorously in the Fifties. Further motivations for the development of direct analysis techniques in applied mechanics of solids and structures arise from the circumstance that in many engineering situations the external actions fluctuate according to time histories not a priori known except for some essential features, e.g. variation intervals. In such situations the critical events (or "limit states") to consider, besides plastic collapse, are incremental collapse (or "ratchetting") and alternating plastic yielding, namely lack of "shakedown". Non evolutionary, direct methods for ultimate limit state analysis of structures subjected to variably-repeated external actions are the objectives of most papers collected in this book, which also contains a few contributions on related topics.
