Available in PDF, EPUB and Kindle. Book excerpt: Ce mémoire porte sur l'analyse du canoë de béton de l'Université Laval, Apogée 2002. L'objectif principal est de comprendre le comportement du canoë sous les divers cas de chargement auxquels il est soumis. Un deuxième objectif est de déterminer des critères de conception pour ce type de structure. Ces critères et la compréhension du comportement serviront de base à la conception des prochains canoës. Ces objectifs sont atteints par un apport combiné de la modélisation et de l'expérimentation. Ce travail discute d'abord de la conception des mélanges de béton utilisés pour la construction du canoë de béton Apogée 2002. La caractérisation des propriétés physiques et mécaniques des composites qui ont servi à la construction de la structure est ensuite présentée. Puis, l'analyse du comportement structural du canoë et de ses sous-structures est réalisée à l'aide d'une analyse par éléments finis. Enfin, des essais in-situ sur le canoë sont effectués et les résultats sont comparés à ceux prédits par le modèle numérique. Les essais expérimentaux comprennent des essais statiques et dynamiques. Les essais dynamiques permettent de déterminer l'amplification des déformations causées par les coups de rame et les virages. Les critères de conception sont déterminés et présentés en fonction des résultats des analyses par éléments finis et finalement des essais expérimentaux.

This book was released on 2019 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Afin de réduire le poids des structures composites et les coûts de fabrication et d'exploitation, le comportement en fatigue des stratifiés carbone fait l'objet d'une grande attention. Les objectifs de cette thèse sont de développer des méthodologies pour évaluer rapidement le comportement en fatigue des stratifiés carbone à partir de l'analyse des données thermodynamiques mesurées par une caméra infrarouge et d'examiner la corrélation entre la dissipation d'énergie et les dommages générés par la fatigue. Trois nouvelles méthodes numériques basées sur l'analyse statistique dans le traitement des données thermiques ont tout d'abord été proposées afin d'éviter les incertitudes humaines dans l'application des méthodes graphiques traditionnelles telles que la méthode de Luong et celle de Risitano. Ces trois méthodes ont toutes été évaluées en déterminant la limite de fatigue avec unicité selon les données expérimentales de la littérature. Ensuite, un modèle à deux paramètres a été proposé pour caractériser la dégradation de la rigidité des stratifiés carbone en fonction de l'augmentation du nombre de cycles. Après la calibration des paramètres et le calcul du seuil de la rigidité normalisée, toute la courbe S-N peut être obtenue dans un temps très court. Ensuite, la relation entre les phénomènes de fatigue et la génération de chaleur est étudiée. En fonction des différentes causes, la chaleur générée a été classée en deux parties : chaleur induite par le frottement interne et celle induite par l'accumulation de dommages. La production totale de chaleur correspondant aux dommages semble être indépendante de l'amplitude de la charge. Cette information peut donc être utilisée pour prédire la courbe S-N avec une bonne précision.

Download or read book Multifunctional Oxide Heterostructures written by Evgeny Y. Tsymbal and published by OUP Oxford. This book was released on 2012-08-30 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the rapidly developing field of oxide thin-films and heterostructures. Oxide materials combined with atomic-scale precision in a heterostructure exhibit an abundance of macroscopic physical properties involving the strong coupling between the electronic, spin, and structural degrees of freedom, and the interplay between magnetism, ferroelectricity, and conductivity. Recent advances in thin-film deposition and characterization techniques made possible the experimental realization of such oxide heterostructures, promising novel functionalities and device concepts. The book consists of chapters on some of the key innovations in the field over recent years, including strongly correlated oxide heterostructures, magnetoelectric coupling and multiferroic materials, thermoelectric phenomena, and two-dimensional electron gases at oxide interfaces. The book covers the core principles, describes experimental approaches to fabricate and characterize oxide heterostructures, demonstrates new functional properties of these materials, and provides an overview of novel applications.
Download or read book Compendium of the Microbiological Spoilage of Foods and Beverages written by Michael P. Doyle and published by Springer Science & Business Media. This book was released on 2009-09-23 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased emphasis on food safety during the past two decades has decreased the emphasis on the loss of food through spoilage, particularly in developed co- tries where food is more abundant. In these countries spoilage is a commercial issue that affects the pro?t or loss of producers and manufacturers. In lesser developed countries spoilage continues to be a major concern. The amount of food lost to spoilage is not known. As will be evident in this text, stability and the type of spoilage are in?uenced by the inherent properties of the food and many other factors. During the Second World War a major effort was given to developing the te- nologies needed to ship foods to different regions of the world without spoilage. The food was essential to the military and to populations in countries that could not provide for themselves. Since then, progress has been made in improved product formulations, processing, packaging, and distribution systems. New products have continued to evolve, but for many new perishable foods product stability continues to be a limiting factor. Many new products have failed to reach the marketplace because of spoilage issues.

Available in PDF, EPUB and Kindle. Book excerpt: This edited monograph contains the proceedings of the International Shock Interaction Symposium, which emerged as an heir to both the Mach Reflection and Shock Vortex Interaction Symposia. These scientific biannual meetings provide an ideal platform to expose new developments and discuss recent challenges in the field of shock wave interaction phenomena. The goal of the symposia is to offer a forum for international interaction between young and established scientists in the field of shock and blast wave interaction phenomena. The target audience of this book comprises primarily researchers and experts in the field of shock waves, but the book may also be beneficial for young scientists and graduate students alike.

Book excerpt: This special volume stems from a symposium 'Granitic Systems - State of the Art and Future Avenues' that was held at the Department of Geology, University of Helsinki to mark the retirement of Professor Ilmari Haapala. The twenty articles in the volume cover a wide range of granite-related topics and focus on three general themes: tectonics and source regions, petrologic processes, and fractionated granites and pegmatites. Both original papers and reviews are included, and the volume will be acknowledged by anyone with a background in Earth Sciences ad a flavor for granitoid rocks. * Comprehensive account of the current status of granite-oriented research * Topics ranging from mineralogy, petrology, and geochemistry to tectonics and crustal evolution

The book provides the reader with the necessary background and current trends in the theoretical and experimental aspects of compressible turbulent flows and compressible turbulence. Detailed derivations of the pertinent equations describing the motion of such turbulent flows is provided and an extensive discussion of the various approaches used in predicting both free shear and wall bounded flows is presented. Experimental measurement techniques common to the compressible flow regime are introduced with particular emphasis on the unique challenges presented by high speed flows. Both experimental and numerical simulation work is supplied throughout to provide the reader with an overall perspective of current trends. - An introduction to current techniques in compressible turbulent flow analysis - An approach that enables engineers to identify and solve complex compressible flow challenges - Prediction methodologies, including the Reynolds-averaged Navier Stokes (RANS) method, scale filtered methods and direct numerical simulation (DNS) - Current strategies focusing on compressible flow control
