Kohn In the past twenty years we have witnessed a renaissance of theoretical work on the macroscopic behavior of microscopically heterogeneous mate rials. This activity brings together a number of related themes, including: ( 1) the use of weak convergence as a rigorous yet general language for the discussion of macroscopic behavior; (2) interest in new types of questions, particularly the "G-closure problem," motivated in large part by applications of optimal control theory to structural optimization; (3) the introduction of new methods for bounding effective moduli, including one based on "com pensated compactness"; and (4) the identification of deep links between the analysis of microstructures and the multidimensional calculus of variations. This work has implications for many physical problems involving optimal design, composite materials, and coherent phase transitions. As a result it has received attention and support from numerous scientific communities, including engineering, materials science, and physics as well as mathematics. There is by now an extensive literature in this area. But for various reasons certain fundamental papers were never properly published, circu lating instead as mimeographed notes or preprints. Other work appeared in poorly distributed conference proceedings volumes. Still other work was published in standard books or journals, but written in Russian or French. The net effect is a sort of "gap" in the literature, which has made the subject unnecessarily difficult for newcomers to penetrate.

Available in PDF, EPUB and Kindle. Book excerpt: L’utilisation des composites à matrice organique pour des applications structurales à haute température est de plus en plus souvent envisagée, notamment dans certaines zones de turbomachines aéronautiques. A cette fin, il devient nécessaire d’analyser les effets du vieillissement thermo-oxydant sur le comportement mécanique d’un polymère et des composites associés. Cet ouvrage met en relief des méthodologies expérimentales originales qui permettent, par analyse inverse, de développer et d’identifier une loi de comportement du polymère dépendant du vieillissement ainsi que les déformations d’origine chimique. Ces informations sont utilisées pour le calcul des contraintes internes induites par un vieillissement thermo-oxydant dans des composites unidirectionnels à fibres continues de carbone. Comportement mécanique des composites à matrice organique se différencie des autres ouvrages par son approche. Il examine des lois de comportement thermomécaniques locales dépendant de l’oxydation grâce à l’emploi d’essais couplés et non couplés à l’échelle microscopique. Il présente des modèles originaux afin d'intégrer toute la richesse de la phénoménologie observée expérimentalement, grâce à l'emploi de variables internes correctement choisies.

Book excerpt: Synthèse unanimement reconnue, Matériaux Composites apporte l'ensemble des éléments nécessaires à une bonne compréhension du comportement mécanique des matériaux et structures composites. Dans ce traité, les différentes parties de l'ouvrage ont été développées de manière à aboutir à une continuité des concepts et théories, fournissant ainsi une approche fondamentale unifiée. Après avoir présenté la constitution puis la mise en œuvre des matériaux composites, l'ouvrage développe progressivement les outils nécessaires à la modélisation du comportement mécanique des structures en matériaux composites stratifiés et sandwichs. Il aborde ensuite les problèmes de dimensionnement des structures montrant comment les outils introduits permettent de modéliser le comportement mécanique. Le contenu et la progression de l'ouvrage ont été conçus avec quatre objectifs principaux : considérer le matériau composite comme un matériau traditionnel ; intégrer l'apport de la conception assistée par ordinateur dans la résolution des problèmes de dimensionnement des structures ; aborder les difficultés de manière progressive afin de faciliter l'accès du lecteur aux divers concepts introduits ; confronter la modélisation avec le comportement réel des matériaux et des structures. Cette quatrième édition, entièrement actualisée, bénéficie de la réalisation de l'ouvrage Composite Materials, de l'auteur. Des exercices ont été ajoutés à la plupart des chapitres. Rigoureux et didactique, Matériaux Composites constitue l'ouvrage de référence des étudiants (2e et 3e cycles), ingénieurs, chercheurs et techniciens supérieurs.

Available in PDF, EPUB and Kindle. Book excerpt: "In recent years, the use of composites and nanocomposites in various aerospace, automotive, marine, and civil engineering applications has been constantly increasing. Without exaggeration, it can be said that it is among the most complex and urgent problems of the mechanics of a deformable solid, since a number of specific phenomena and difficultly taken into account analytic factors arise during cyclic loading. They are primarily associated with the development of fatigue damage, with the need to assess the cyclic and structural instability of composite and nanocomposite materials. Currently, the problem of structural strength under cyclic loading is considered much more widely. This is due to the development of new industries in modern technology, such as aircraft, power engineering, aviation and rocket technology. The cyclic loading significantly reduces the creep resistance in the entire frequency range, and it became obvious that such traditional characteristics of strength as endurance limit, static creep limits and long-term static strength can no longer suffice the design criteria for reliable performance. As a result, new directions appeared in the section of high-temperature strength - cyclical creep and long-term cyclic strength. These circumstances led to the creation of new methods and means of determining the resistance of composites and nanocomposites materials and continuum damage development under cyclic loading; to the creation of appropriate physical models. Particularly relevant is the intensification of creep by high-frequency cyclic loading in composite materials, which usually occurs at high temperatures. Most of the known studies in the field of cyclic creep are experimental, and the direct use of number of cycles to define damage model cannot escape the empirical relation that predicts multi-stress level fatigue life well"--

Available in PDF, EPUB and Kindle. Book excerpt: L’un des enjeux en contrôle de santé des structures est la détection précoce de l’endommagement avant que ce dernier ne conduise à la ruine. Dans ce contexte, l’émission acoustique est une technique bien adaptée afin de suivre, en temps réel, l’état de santé d’une structure ou des matériaux qui la constituent. En effet, les mécanismes d’endommagement s’accompagnent de libération d’énergie sous forme d’ondes acoustiques. Des capteurs disposés à la surface de structures ou d’éprouvettes de laboratoire permettent d’enregistrer les signaux d’EA. Cet ouvrage est dédié à l’identification de la signature acoustique des différents mécanismes d’endommagement se produisant dans les matériaux composites à matrice organique, mais aussi dans les matériaux composites à matrice céramique. Les apports de cette approche sont présentés, ainsi que les principales difficultés et les limites. Aussi, la prévision de la durée de vie à l’aide de l’EA pour des essais de longues durées est discutée.

This book was released on 2011-07-14 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue has long been recognized as a mechanism that can provoke catastrophic material failure in structural applications and researchers are now turning to the development of prediction tools in order to reduce the cost of determining design criteria for any new material. Fatigue of Fiber-reinforced Composites explains these highly scientific subjects in a simple yet thorough way. Fatigue behavior of fiber-reinforced composite materials and structural components is described through the presentation of numerous experimental results. Many examples help the reader to visualize the failure modes of laminated composite materials and structural adhesively bonded joints. Theoretical models, based on these experimental data, are demonstrated and their capacity for fatigue life modeling and prediction is thoroughly assessed. Fatigue of Fiber-reinforced Composites gives the reader the opportunity to learn about methods for modeling the fatigue behavior of fiber-reinforced composites, about statistical analysis of experimental data, and about theories for life prediction under loading patterns that produce multiaxial fatigue stress states. The authors combine these theories to establish a complete design process that is able to predict fatigue life of fiber-reinforced composites under multiaxial, variable amplitude stress states. A classic design methodology is presented for demonstration and theoretical predictions are compared to experimental data from typical material systems used in the wind turbine rotor blade industry. Fatigue of Fiber-reinforced Composites also presents novel computational methods for modeling fatigue behavior of composite materials, such as artificial neural networks and genetic programming, as a promising alternative to the conventional methods. It is an ideal source of information for researchers and graduate students in mechanical engineering, civil engineering and materials science.

This book was released on 1999 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: la thèse porte sur la prédiction des mécanismes d'endommagement qui se développent au sein des composites stratifies. La modélisation de tels mécanismes est basée sur une mesomodelisation, élaborée au l.m.t.-cachan, et developpee depuis près de 15 ans. Des progrès restent a faire au niveau de la simulation, car les méthodes incrémentales classiques ne sont pas adaptées aux phénomènes alliant de nombreuses difficultés (localisation brutale, endommagement), et la thèse concerne l'élaboration d'une méthode de résolution rapide et robuste, visant a réduire considérablement les coûts, et a maîtriser les calculs. Cette stratégie de résolution est basée sur la méthode latin, non-incrementale, proposée par ladeveze en 1985. Cette approche, appliquée à de nombreux problèmes par ailleurs, a montre d'importants intérêts pour le traitement de problème de grandes tailles. afin d'en vérifier la faisabilité, l'extension de cette méthode aux cas des matériaux adoucissants s'est concrétisée par la mise en uvre sous matlab d'un logiciel prototype, dédie a la résolution de problèmes unidimensionnels elasto-plasto-endommageables, décrivant avec robustesse la ruine complète par endommagement du matériau. Par ailleurs, un estimateur d'erreur a été défini, afin de pouvoir valider les calculs déjà effectues. Cet estimateur, base sur la notion d'erreur en relation de comportement, étend le concept d'erreur en dissipation aux matériaux endommageables. Lorsque le comportement est exprime sous forme standard, on construit 2 contributions a l'erreur, l'une sur les lois d'état et l'autre sur les lois d'évolution, en utilisant les propriétés de la transformée de legendre-fenchel, a partir des potentiels convexes régissant les lois de comportement. Cet estimateur d'erreur est utilise comme critère d'arrêt de l'algorithme itératif latin, et permet en outre l'adaptation des paramètres de discrétisation par un contrôle fin du calcul d'une part, et une diminution du coût de celui-ci d'autre part.
