Available in PDF, EPUB and Kindle. Book excerpt: Les objectifs de la mécanique de la rupture sont double, d'une part ils concernent la description des champs mécaniques au voisinage de la pointe de la fissure et les énergies qui leur sont associées et d'autre part, ils traitent de l'évaluation de la nocivité d'une fissure en terme de la propagation de celle-ci. Deux champs d'étude constituent la structure de cet ouvrage, l'un relatif à la modélisation de la singularité induite par la pointe d'une fissure qui est relatée dans le premier tome intitulé : Modélisation des champs mécaniques en pointe de fissure et des singularités. Après un premier volume intitulé "Mécanique de la rupture par fissuration", ce deuxième tome traite des critères de propagation et de bifurcation de fissure en milieu élastique et élastoplastique sous des chargements monotones (Rupture fragile) et dynamique (Rupture par Fatigue). Les solutions analytiques obtenues ne peuvent pas être utilisées dans les structures à géométrie et conditions aux limites variées, alors il sera nécessaire de faire appel aux méthodes d'analyse numérique et plus particulièrement à la méthode des éléments finis. Deux chapitres abordent ces applications numériques : l'un, en tome I, relatif à l'introduction au calcul par éléments finis des structures fissurées et l'autre, dans le tome II traitant de la prévision de la rupture par fissuration des éléments de structures métalliques soumises à la fatigue.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent advances related to the following two topics: how mechanical fields close to material or geometrical singularities such as cracks can be determined; how failure criteria can be established according to the singularity degrees related to these discontinuities. Concerning the determination of mechanical fields close to a crack tip, the first part of the book presents most of the traditional methods in order to classify them into two major categories. The first is based on the stress field, such as the Airy function, and the second resolves the problem from functions related to displacement fields. Following this, a new method based on the Hamiltonian system is presented in great detail. Local and energetic approaches to fracture are used in order to determine the fracture parameters such as stress intensity factor and energy release rate. The second part of the book describes methodologies to establish the critical fracture loads and the crack growth criteria. Singular fields for homogeneous and non-homogeneous problems near crack tips, v-notches, interfaces, etc. associated with the crack initiation and propagation laws in elastic and elastic-plastic media, allow us to determine the basis of failure criteria. Each phenomenon studied is dealt with according to its conceptual and theoretical modeling, to its use in the criteria of fracture resistance; and finally to its implementation in terms of feasibility and numerical application. Contents 1. Introduction. Part 1: Stress Field Analysis Close to the Crack Tip 2. Review of Continuum Mechanics and the Behavior Laws. 3. Overview of Fracture Mechanics. 4. Fracture Mechanics. 5. Introduction to the Finite Element Analysis of Cracked Structures. Part 2: Crack Growth Criteria 6. Crack Propagation. 7.

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.

Available in PDF, EPUB and Kindle. Book excerpt: La fiabilité anticipe et prévoit le futur en vue d’améliorer les performances et le niveau de sûreté par l’optimisation des stratégies d’exploitation. Elle a fait preuve d’une évolution notable au niveau des matériaux et des structures. Largement inspiré des modèles de la mécanique de rupture, cet ouvrage présente les cas les plus significatifs dont l’encadrement de la probabilité de rupture par les bornes simples, la méthode Bayésienne appliquée, les chaînes de Markov, les indices de fiabilité de Cornell et de Hasofer-Lind ou l’intégrale indicatrice du dommage et de la simulation de Monte Carlo. Ce volume insiste sur le calcul des incertitudes au sens de la méthode GUM (Guide to the expression of Uncertainty in Measurement) en respectant le vocabulaire international de métrologie. Destiné aux universitaires et aux professionnels, Fiabilité mécanique appliquée se caractérise par son approche pédagogique des méthodes statistiques, structurées autour de cas concrets et illustrées d’applications corrigées et commentées. Ce volume apportera une aide précieuse aux concepteurs et aux décideurs.

Available in PDF, EPUB and Kindle. Book excerpt: The design of mechanical structures with improved and predictable durability cannot be achieved without a thorough understanding of the mechanisms of fatigue damage and more specifically the relationships between the microstructure of materials and their fatigue properties. Written by leading experts in the field, this book (which is complementary to Fatigue of Materials and Structures: Application to Damage and Design, also edited by Claude Bathias and André Pineau), provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, polymers and composites. Each chapter is devoted to one of the major classes of materials or to different types of fatigue damage, thereby providing overall coverage of the field. The book deals with crack initiation, crack growth, low-cycle fatigue, gigacycle fatigue, shorts cracks, fatigue micromechanisms and the local approach to fatigue damage, corrosion fatigue, environmental effects and variable amplitude loadings, and will be an important and much used reference for students, practicing engineers and researchers studying fracture and fatigue in numerous areas of mechanical, structural, civil, design, nuclear, and aerospace engineering as well as materials science.

Available in PDF, EPUB and Kindle. Book excerpt: The failure of any welded joint is at best inconvenient and at worst can lead to catastrophic accidents. Fracture and fatigue of welded joints and structures analyses the processes and causes of fracture and fatigue, focusing on how the failure of welded joints and structures can be predicted and minimised in the design process.Part one concentrates on analysing fracture of welded joints and structures, with chapters on constraint-based fracture mechanics for predicting joint failure, fracture assessment methods and the use of fracture mechanics in the fatigue analysis of welded joints. In part two, the emphasis shifts to fatigue, and chapters focus on a variety of aspects of fatigue analysis including assessment of local stresses in welded joints, fatigue design rules for welded structures, k-nodes for offshore structures and modelling residual stresses in predicting the service life of structures.With its distinguished editor and international team of contributors, Fracture and fatigue of welded joints and structures is an essential reference for mechanical, structural and welding engineers, as well as those in the academic sector with a research interest in the field. - Analyses the processes and causes of fracture and fatigue, focusing predicting and minimising the failure of welded joints in the design process - Assesses the fracture of welded joints and structure featuring constraint-based fracture mechanics for predicting joint failure - Explores specific considerations in fatigue analysis including the assessment of local stresses in welded joints and fatigue design rules for welded structures
