Book excerpt: Les méthodes de calcul en fatigue à grande durée de vie sont en cours de développement depuis des décennies et sont utilisées par les ingénieurs pour dimensionner les structures. Généralement, ces méthodes se basent sur la mise en équations de quantités mécaniques calculées à l'échelle macroscopique ou mésoscopique. Les critères de fatigue multiaxiale reposent généralement sur des hypothèses de changement d'échelle dont l'objectif est d'accéder à l'état de contraintes ou de déformations à l'échelle du grain. Dans les approches de type plan critique (Dang Van, Papadopoulos, Morel), l'amorçage d'une fissure de fatigue est considéré comme piloté par une quantité mécanique liée à une orientation matérielle particulière (plan critique). Si ces phénomènes sont bien établis dans le cas des chargements uniaxiaux, la nature des mécanismes liés à l'activation des systèmes de glissement, à la multiplicité du glissement et aux différents sites préférentiels d'amorçage de fissures sous chargements complexes reste peu connue.Afin de mieux comprendre les mécanismes d'endommagement en fatigue multiaxiale, les techniques d'analyse et de caractérisation de l'activité plastique (activation des systèmes de glissements, bandes de glissement persistantes) et d'observation de l'endommagement par fatigue ont été mises en place en se basant principalement sur des observations MEB et analyses EBSD. Ces investigations ont permis de mettre en lumière les effets des chargements non proportionnels sur la multiplicité du glissement sur du cuivre pur OFHC. L'étude statistique des sites préférentiels d'amorçage de fissures montre que les grains à glissement multiple présentent une forte probabilité d'amorçage de fissures, surtout sous les chargements non proportionnels. Nous avons également mis en évidence le rôle des joints de grains et des joints de macle sur le développement de la plasticité à l'échelle de la microstructure. Les résultats expérimentaux sont confrontés à ceux du calcul éléments finis (EF) en plasticité polycristalline sur des microstructures synthétiques 3D semi-périodiques. L'application du critère de Dang Van à l'échelle mésoscopique (le grain) montre une forte variabilité de la contrainte hydrostatique et du cisaillement. Cette variabilité est plus importante pour un modèle de comportement cristallin élastique anisotrope. Le rôle de la plasticité cristalline se révèle secondaire. Ces analyses permettent de remettre en perspective les hypothèses usuelles de changement d'échelle utilisées en fatigue multiaxiale. Enfin, une méthode basée sur la statistique des valeurs extrêmes est proposée pour le dépouillement des calculs EF sur agrégats. Cette analyse a été appliquée sur la contrainte équivalente associée au critère de fatigue de Dang Van pour les calculs d'agrégats polycristallins avec différentes morphologies et orientations des grains. Les effets de la surface libre, du type de chargement et du modèle de comportement mécanique des grains ont été analysés. Les résultats offrent des perspectives intéressantes sur la modélisation de l'amorçage des fissures en fatigue multiaxiale des matériaux et des structures avec une prise en compte de la microstructure.

Book Synopsis Multiaxial Notch Fatigue by : Luca Susmel
Download or read book Multiaxial Notch Fatigue written by Luca Susmel and published by Elsevier. This book was released on 2009-03-20 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal and composite components used in structural engineering not only contain geometrical features resulting in stress concentration phenomena, but they are also subjected to in-service multiaxial fatigue loading. To address the problem, structural engineers need reliable methodologies which allow for an adequate margin of safety. The book summarises methods devised by the author to design real components against multiaxial fatigue by taking full advantage not only of nominal but also of local stress-strain quantities.The book begins by reviewing definitions suitable for calculating the stress-strain quantities commonly used to perform fatigue assessment. The Modified Wöhler Curve Method is then explained in detail, by focusing attention on both the high- and the medium-cycle fatigue regime. The existing links between the multiaxial fatigue criterion and physical properties are also discussed. A procedure suitable for employing the method developed by the author to estimate fatigue damage both in notched and in welded components is explained. The Modified Manson-Coffin Curve method is investigated in depth, by reviewing those concepts playing a fundamental role in the so-called strain based approach. Lastly, the problem of performing the fatigue assessment of composite materials is addressed by considering design parameters influencing composite behaviour under complex cyclic loading paths and those criteria suitable for designing real components against multiaxial fatigue. The book also contains two appendices summarising experimental data from the technical literature. These appendices provide a unique and highly valuable resource for engineers. The appendices summarise around 100 values of the material characteristic length L, experimentally determined by testing specimens made of different engineering materials and about 4500 experimental fatigue results generated by testing plain, notched and welded specimens under constant-amplitude proportional and non-proportional multiaxial fatigue loading are listed. Summarises methods devised by the author to design real components against multiaxial fatigue Reviews definitions suitable for calculating the stress-strain quantities commonly used to perform fatigue assessment Includes an in-depth explanation of both the Modified Wöhler Curve and Modified Manson-Coffin Curve Method

Book Synopsis Tracer Diffusion Data for Metals, Alloys, and Simple Oxides by : John Askill
Download or read book Tracer Diffusion Data for Metals, Alloys, and Simple Oxides written by John Askill and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic diffusion in metals was first discovered some sixty-five years ago, and since then a considerable wealth of data has ac cumulated on diffusion in various systems. However, work prior to about the year 1940 is now mainly of historical interest, since ex periments were often carried out under experimental conditions and with methods of analysis leading to uncertainties in inter preting the measured diffusion coefficients. Data on diffusion rates are of importance in processes which are controlled by rates of atomic migration such as growth of phases and homogenization of alloys. In addition diffusion plays an important part in theories of such phenomena as oxidation, plastic deformation, sintering, and creep. A tremendous advance in diffusion studies was made possible by the availability of radioactive isotopes of sufficiently high spe cific activity after the second world war. Measurements of self diffusion rates then became possible using radioactive isotopes having the same chemical properties as the solvent material, and it also became possible to study tracer impurity diffusion when the concentration of the impurity is so small as not to alter the chemi cal homogeneity of the system. In the last ten to fifteen years the purity of materials used in diffusion studies has increased con siderably and the methods of analysis have become more stand ardized.

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.

Book Synopsis Non-Linear Mechanics of Materials by : Jacques Besson
Download or read book Non-Linear Mechanics of Materials written by Jacques Besson and published by Springer Science & Business Media. This book was released on 2009-11-25 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: In mechanical engineering and structural analysis there is a significant gap between the material models currently used by engineers for industry applications and those already available in research laboratories. This is especially apparent with the huge progress of computational possibilities and the corresponding dissemination of numerical tools in engineering practice, which essentially deliver linear solutions. Future improvements of design and life assessment methods necessarily involve non-linear solutions for inelastic responses, in plasticity or viscoplasticity, as well as damage and fracture analyses. The dissemination of knowledge can be improved by software developments, data base completion and generalization, but also by information and training. With such a perspective Non-Linear Mechanics of Materials proposes a knowledge actualization, in order to better understand and use recent material constitutive and damage modeling methods in the context of structural analysis or multiscale material microstructure computations.
Book Synopsis Temperature-Fatigue Interaction by : L. Remy
Download or read book Temperature-Fatigue Interaction written by L. Remy and published by Elsevier. This book was released on 2002-03-11 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of peer-reviewed papers presented at the International Conference on Temperature-Fatigue Interaction, held in Paris, May 29-31, 2001, organised by the Fatigue Committee of the Societé Française de Métallurgie et de Matériaux (SF2M), under the auspices of the European Structural Integrity Society. The conference disseminated recent research results and promoting the interaction and collaboration amongst materials scientists, mechanical engineers and design engineers. Many engineering components and structures used in the automotive, aerospace, power generation and many other industries experience cyclic mechanical loads at high temperature or temperature transients causing thermally induced stresses. The increase of operating temperature and thermal mechanical loading trigger the interaction with time-dependent phenomena such as creep and environmental effects (oxidation, corrosion). A large number of metallic materials were investigated including aluminium alloys for the automotive industry, steels and cast iron for the automotive industry and materials forming, stainless steels for power plants, titanium, composites, intermetallic alloys and nickel base superalloys for aircraft industry, polymers. Important progress was observed in testing practice for high temperature behaviour, including environment and thermo-mechanical loading as well as in observation techniques. A large problem which was emphasized is to know precisely service loading cycles under non-isothermal conditions. This was considered critical for numerous thermal fatigue problems discussed in this conference.

Available in PDF, EPUB and Kindle. Book excerpt: Since its inception in 1991, EUROMAT has been held each year on behalf of the Federation of European Materials Societies (FEMS), and alternates between general and topical prospectives. This year's theme, Advances in Mechanical Behaviour, Plasticity and Damage, was proposed by the Societe Francaise de Metallurgie et de Materiaux (SF2M) to FEMS. This publication contains a selection of papers presented at the EUROMAT 2000 Conference, held in Tours, France on 7-9 November 2000. The aim of this Conference was to concentrate mainly on recent advances made in the investigation of the relationship between microstructures of materials and their mechanical behaviour; including, fundamentals, modelling and applications. Encompassed in the Conference's aim is the nurturing of the synergistic effect between the theoretical and applied areas in this field. This was achieved by addressing important basic and practical aspects of the mechanical behaviour and damage of materials whilst also providing significant links between various complementary approaches. All kinds of materials are covered and topics that were covered include the mechanics of solid polymers, microstructurs and micromechanisms, and the collective behavior of defects which looks at the interaction of multiple defects in a system.
