Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 2002 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le collage externe de matériaux composites s'avère comme une méthode prometteuse pour la réparation de structures de génie civil. La mise en oeuvre de cette technique est relativement simple. Elle est de surcroît intéressante d'un point de vue économique. Cependant, si elle apporte de nouvelles solutions, elle entraîne aussi des problèmes spécifiques. En particulier, le mode de rupture par peeling-off du béton d'enrobage sous-jacent au renfort composite présente un caractère fragile. Il est provoqué par la concentration de contraintes dans la zone d'ancrage à l'extrémité du renfort. Le présent travail cherche à étudier les phénomènes dont cette zone est le siège afin de proposer une méthode de calcul pour son dimensionnement. Une étude à la fois analytique, expérimentale et numérique a été conduite dans ce but. Dans un premier temps, une analyse bibliographique montre la diversité des méthodes et des approches existantes pour modéliser le comportement de la zone d'ancrage et pour prédire la contrainte maximale dans le joint de colle entre le composite et le béton. Des modèles analytiques, très rigoureux mais complexes, et des modèles empiriques, plus simples à manipuler, ont été trouvés dans la littérature. Partant de ces éléments, un modèle analytique est proposé dans la continuité de l'analyse bibliographique. Il résume et unifie les modèles déjà disponibles en donnant les expressions analytiques des distributions des déformations et des contraintes dans la liaison béton composite. Dans un deuxième temps, une étude expérimentale du mécanisme d'interaction béton/composite a été menée. Elle comprend des essais de compression, de traction et de flexion. Les essais ont été réalisés du cas le plus simple (compression axiale) au plus complexe (moment fléchissant plus effort tranchant) en terme de chargement et de réponse structurelle. Ainsi, les résultats des essais de compression constituent une aide précieuse pour définir les essais de traction et analyser les résultats qui en découlent. De même, les essais de traction aident à définir puis à analyser les essais de flexion. Des corps d'épreuve de taille réduite en béton armé renfocés avec des plaques unidirectionnelles en carbone/époxyde ont été utilisés. L'instrumentation est basée principalement sur les jauges de déformation collées sur le béton et le renfort composite et sur des techniques de mesure optiques qui permettent de suivre l'évolution de la fissuration dans la zone d'ancrage et de mettre en évidence de manière précise le mécanisme de rupture par peeling-off. La confrontation des résultats expérimentaux et analytiques montre un décalage entre théorie et expérimentation. Des calculs par éléments finis confirment les résultats expérimentaux et mettent en évidence la carence du modèle analytique. Cette analyse comparative a permis de proposer une correction du modèle analytique pour compenser cette insuffisance. La modélisation numérique fournit aussi des éléments pour évaluer l'influence de la fissuration sur la répartition des contraintes à l'interface dans la zone d'ancrage. Sur cette base, un critère de rupture par peeling-off est proposé. Finalement, une règle simple de dimensionnement des éléments sollicités en traction ou flexion est proposée dans la dernière partie de ce travail à partir de l'ensemble des résultats obtenus

This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.
Download or read book Plates Laminates And Shells Asymptotic Analysis And Homogenization written by Tomasz Lewinski and published by World Scientific. This book was released on 2000-03-23 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a systematic and comprehensive presentation of the results concerning effective behavior of elastic and plastic plates with periodic or quasiperiodic structure. One of the chapters covers the hitherto available results concerning the averaging problems in the linear and nonlinear shell models.A unified approach to the problems studied is based on modern variational and asymptotic methods, including the methods of variational inequalities as well as homogenization techniques. Duality arguments are also exploited. A significant part of the book deals with problems important for engineering practice, such as: statical analysis of highly nonhomogeneous plates and shells for which common discretization techniques fail to be efficient, assessing stiffness reduction of cracked [00n/900m]s laminates, and assessing ultimate loads for perfectly plastic plates and shells composed of repeated segments. When possible, the homogenization formulas are cast in closed form expressions. The formulas presented in this manner are then used in constructing regularized formulations of the fundamental optimization problems for plates and shells, since the regularization concepts are based on introducing the composite regions for which microstructural properties play the role of new design variables.

Download or read book The Planetarium written by Nathalie Sarraute and published by Deep Vellum Publishing. This book was released on 2023-01-31 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: A young writer has his heart set on his aunt's large apartment. With this seemingly simple conceit, the characters of The Planetarium are set in orbit and a galaxy of argument, resentment, and bitterness erupts. Telling the story from various points of view, Sarraute focuses below the surface, on the emotional lives of the characters in a way that surpasses even Virginia Woolf. Always deeply engaging, The Planetarium reveals the deep disparity between the way we see ourselves and the way others see us.
