This book was released on 1998 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail concerne le développement de modèles éléments finis de type poutre pour l'analyse non linéaire géométrique des structures flexibles. Ces modèles considèrent une représentation complète des effets dus aux grandes rotations 3D. Mis à part la cinématique de structures minces, aucune hypothèse restrictive n'est adoptée dans la formulation du problème en efforts résultants. La première partie du document est consacrée à l'étude des problèmes de déformation statique et dynamique et à leur résolution par la méthode des éléments finis. Trois éléments finis basés sur différentes paramétrisations des grandes rotations sont construits et implantes, et le schéma d'intégration temporelle de Newmark est adapté à chacun de ces éléments. Dans la deuxième partie, nous exploitons ces modèles dans l'étude de l'instabilité non linéaire des structures constituées de poutres : - une méthode de calcul des charges critiques par la procédure itérative de newton est considérée afin d'éviter la limitation de la méthode du flambement linéaire au cas des petites rotations. - une approche de post-flambement dynamique est présentée dans le but de simuler le claquement des structures minces qui apparait au delà d'un point critique.

Book excerpt: Since the middle of the 20th Century yield design approaches have been identified with the lower and upper bound theorem of limit analysis theory – a theory associated with perfect plasticity. This theory is very restrictive regarding the applicability of yield design approaches, which have been used for centuries for the stability of civil engineering structures. This book presents a theory of yield design within the original “equilibrium/resistance” framework rather than referring to the theories of plasticity or limit analysis; expressing the compatibility between the equilibrium of the considered structure and the resistance of its constituent material through simple mathematical arguments of duality and convex analysis results in a general formulation, which encompasses the many aspects of its implementation to various stability analysis problems. After a historic outline and an introductory example, the general theory is developed for the three-dimensional continuum model in a versatile form based upon simple arguments from the mathematical theory of convexity. It is then straightforwardly transposed to the one-dimensional curvilinear continuum, for the yield design analysis of beams, and the two-dimensional continuum model of plates and thin slabs subjected to bending. Field and laboratory observations of the collapse of mechanical systems are presented along with the defining concept of the multi-parameter loading mode. The compatibility of equilibrium and resistance is first expressed in its primal form, on the basis of the equilibrium equations and the strength domain of the material defined by a convex strength criterion along with the dual approach in the field of potentially safe loads, as is the highlighting of the role implicitly played by the theory of yield design as the fundamental basis of the implementation of the ultimate limit state design (ULSD) philosophy with the explicit introduction of resistance parameters.

Download or read book The Franks in the Aegean written by Peter Lock and published by Routledge. This book was released on 2014-01-14 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the enormous literature on the crusades, the Frankish states in the Aegean (set up in the wake of the Fourth Crusade in 1204) have been seriously neglected by modern historians. Yet their history is both compelling in itself - these were the last crusader states to be set up in the eastern Mediterranean and among the last to fall to the Turks - and also valuable for the case study they offer in medieval colonialism. Peter Lock surveys the social, economic, religious and cultural aspects of the region within a broad political framework, and explores the clash of cultures between the Frankish interlopers and their Byzantine subjects. This is a major addition to crusading studies.

Download or read book Optimal Shape Design for Elliptic Systems written by O. Pironneau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of optimal shape design can be arrived at by asking the following question: "What is the best shape for a physical system?" This book is an applications-oriented study of such physical systems; in particular, those which can be described by an elliptic partial differential equation and where the shape is found by the minimum of a single criterion function. There are many problems of this type in high-technology industries. In fact, most numerical simulations of physical systems are solved not to gain better understanding of the phenomena but to obtain better control and design. Problems of this type are described in Chapter 2. Traditionally, optimal shape design has been treated as a branch of the calculus of variations and more specifically of optimal control. This subject interfaces with no less than four fields: optimization, optimal control, partial differential equations (PDEs), and their numerical solutions-this is the most difficult aspect of the subject. Each of these fields is reviewed briefly: PDEs (Chapter 1), optimization (Chapter 4), optimal control (Chapter 5), and numerical methods (Chapters 1 and 4).

Download or read book The Archaeology of Medieval Greece written by Peter Lock and published by Oxbow Books Limited. This book was released on 1996 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greece's importance in the Middle Ages is often neglected by those more concerned with its Prehistoric or Classical past. But, as the colony of Frankish and Italian maritime Empires and as a haven for the Orthodox Church after the fall of Constantinople, the landscape of Greece is covered in a profusion of Medieval art and architecture. This text brings this heritage back to public attention.
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated 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 dissemination phases of the ac· tivity 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 volume 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 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

This book was released on 2017-03-14 with total page 1068 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here are over 1,000 pages of authoritative information on the archaeology of Greek and Roman civilization. The sites discussed in the more than 2,800 entries are scattered from Britain to India and from the shores of the Black Sea to the coast of North Africa and up the Nile. They are located on sixteen area maps, keyed to the entries. The entries were written by 375 scholars from sixteen nations, many of whom have worked at the sites they describe. Until now our knowledge of the Classical period has been scattered in hundreds of sources dating from antiquity to our own times. This volume provides essential information on work accomplished, in progress, and still to be undertaken. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Download or read book Optimal Shape Design written by B. Kawohl and published by Springer Science & Business Media. This book was released on 2000-11-16 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimal Shape Design is concerned with the optimization of some performance criterion dependent (besides the constraints of the problem) on the "shape" of some region. The main topics covered are: the optimal design of a geometrical object, for instance a wing, moving in a fluid; the optimal shape of a region (a harbor), given suitable constraints on the size of the entrance to the harbor, subject to incoming waves; the optimal design of some electrical device subject to constraints on the performance. The aim is to show that Optimal Shape Design, besides its interesting industrial applications, possesses nontrivial mathematical aspects. The main theoretical tools developed here are the homogenization method and domain variations in PDE. The style is mathematically rigorous, but specifically oriented towards applications, and it is intended for both pure and applied mathematicians. The reader is required to know classical PDE theory and basic functional analysis.

Available in PDF, EPUB and Kindle. Book excerpt: "According to one myth, the first Athenian citizen was born from the earth after the sperm of a rejected lover, the god Hephaistos, dripped off the virgin goddess Athena's leg and onto fertile soil. Henceforth Athenian citizens could claim to be truly indigenous to their city and to have divine origins that bypassed maternity. In these essays, the renowned French Hellenist Nicole Loraux examines the implication of this and other Greek origin myths as she explores how Athenians in the fifth century forged and maintained a collective identity."--Publisher's description.
