Book Synopsis Méthode des éléments finis en mécanique des structures by : Thomas Gmür
Download or read book Méthode des éléments finis en mécanique des structures written by Thomas Gmür and published by EPFL Press. This book was released on 2000-01-01 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Une étape primordiale dans la conception et l'optimisation des structures complexes est l'établissement d'un modèle numérique de base, affiné successivement par des essais expérimentaux pour être finalement validé. Cette phase de modélisation, essentielle pour une compréhension future du comportement du système sous différentes sollicitations, suppose le recours à un outil d'analyse numérique performant et maîtrisable, s'appuyant généralement sur la méthode des éléments finis. Cet ouvrage a pour dessein d'exposer les fondements de la méthode des éléments finis et de montrer les qualités - mais aussi les limites - de ce procédé qui constitue à l'heure actuelle la technique la plus répandue de discrétisation spatiale. Son originalité réside dans l'analyse méthodique des problèmes elliptiques du second ordre monodimensionnels, bidimensionnels à variable d'état scalaire et tridimensionnels à variable d'état vectorielle, depuis leur formulation forte classique jusqu'à l'approche locale par la méthode des éléments finis. Mathématiquement rigoureux sans sacrifier les aspects pratiques, l'ouvrage passe systématiquement en revue les formes intégrale, faible et discrète des classes de problèmes couramment rencontrés en mécanique appliquée pour aboutir à une élaboration unifiée d'un modèle d'éléments finis. Comme en témoignent les nombreux exemples et exercices simples qui jalonnent l'exposé, le livre s'adresse en priorité aux étudiants de début de deuxième cycle. Bien que conçu à la base comme support d'enseignement, il est aussi destiné aux chercheurs et ingénieurs praticiens qui désirent s'initier à la méthode des éléments finis.

Book Synopsis Méthode des éléments finis by : Michel Cazenave
Download or read book Méthode des éléments finis written by Michel Cazenave and published by . This book was released on 2010 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: La méthode des éléments finis permet de résoudre numériquement des équations aux dérivées partielles clans le domaine des structures, de la thermodynamique, ou encore de la mécanique des fluides. Cet ouvrage propose d'aborder la méthode par la pratique à travers 16 exemples de complexité croissante : Partant de rappels en mathématiques et en mécanique du solide, le principe d'approximation élémentaire est tout d'abord appliqué aux structures filaires en barres et poutres. La problématique du maillage et de la validation des modèles de calcul est ensuite abordée lors de l'étude de modélisations surfaciques d'éléments divers (membranes, plaques et coques). Enfin, ces différents éléments sont ensuite utilisés dans le cadre de l'étude de la non-linéarité géométrique et des méthodes de résolution associées. La méthode est accompagnée de calculs manuels ou semi-automatiques effectués avec le logiciel Mathcad dont les résultats sont recoupés avec les codes de calcul Advance Structure/Effel ou Abaqus. Véritable outil de référence, cet ouvragea pour objectif de familiariser les ingénieurs, les techniciens mais également les étudiants à la méthode des éléments finis, dont l'utilisation s'est généralisée dans l'industrie depuis une vingtaine d'années.
Book Synopsis The History of the Theory of Structures by : Karl-Eugen Kurrer
Download or read book The History of the Theory of Structures written by Karl-Eugen Kurrer and published by John Wiley & Sons. This book was released on 2018-07-23 with total page 1242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zehn Jahre nach der 1. Auflage in englischer Sprache legt der Autor sein Buch The History of the Theory of Structures in wesentlich erweiterter Form vor, nunmehr mit dem Untertitel Searching for Equilibrium. Mit dem vorliegenden Buch lädt der Verfasser seine Leser zur Suche nach dem Gleichgewicht von Tragwerken auf Zeitreisen ein. Die Zeitreisen setzen mit der Entstehung der Statik und Festigkeitslehre eines Leonardo und Galilei ein und erreichen ihren ersten Höhepunkt mit den baustatischen Theorien über den Balken, Erddruck und das Gewölbe von Coulomb am Ende des 18. Jahrhunderts. Im folgenden Jahrhundert formiert sich die Baustatik mit Navier, Culmann, Maxwell, Rankine, Mohr, Castigliano und Müller-Breslau zu einer technikwissenschaftlichen Grundlagendisziplin, die im 20. Jahrhundert in Gestalt der modernen Strukturmechanik bei der Herausbildung der konstruktiven Sprache des Stahl-, Stahlbeton-, Flugzeug-, Automobil- und des Schiffbaus eine tragende Rolle spielt. Dabei setzt der Autor den inhaltlichen Schwerpunkt auf die Formierung und Entwicklung moderner numerischer Ingenieurmethoden wie der Finite-Elemente-Methode und beschreibt ihre disziplinäre Integration in der Computational Mechanics. Kurze, durch historische Skizzen unterstützte Einblicke in gängige Berechnungsverfahren erleichtern den Zugang zur Geschichte der Strukturmechanik und Erddrucktheorie vom heutigen Stand der Ingenieurpraxis und stellen einen auch einen wichtigen Beitrag zur Ingenieurpädagogik dar. Dem Autor gelingt es, die Unterschiedlichkeit der Akteure hinsichtlich ihres technisch-wissenschaftlichen Profils und ihrer Persönlichkeit plastisch zu schildern und das Verständnis für den gesellschaftlichen Kontext zu erzeugen. So werden in 260 Kurzbiografien die subjektive Dimension der Baustatik und der Strukturmechanik von der frühen Neuzeit bis heute entfaltet. Dabei werden die wesentlichen Beiträge der Protagonisten der Baustatik besprochen und in die nachfolgende Bibliografie integriert. Berücksichtigt wurden nicht nur Bauingenieure und Architekten, sondern auch Mathematiker, Physiker, Maschinenbauer sowie Flugzeug- und Schiffbauer. Neben den bekannten Persönlichkeiten der Baustatik, wie Coulomb, Culmann, Maxwell, Mohr, Müller-Breslau, Navier, Rankine, Saint-Venant, Timoshenko und Westergaard, wurden u. a. auch G. Green, A. N. Krylov, G. Li, A. J. S. Pippard, W. Prager, H. A. Schade, A. W. Skempton, C. A. Truesdell, J. A. L. Waddell und H. Wagner berücksichtigt. Den Wegbereitern der Moderne in der Baustatik J. H. Argyris, R. W. Clough, Th. v. Kármán, M. J. Turner und O. C. Zienkiewicz wurden umfangreiche Biografien gewidmet. Eine ca. 4500 Titel umfassende Bibliografie rundet das Werk ab. Neue Inhalte der 2. Auflage sind: Erddrucktheorie, Traglastverfahren, historische Lehrbuchanalyse, Stahlbrückenbau, Leichtbau, Platten- und Schalentheorie, Greensche Funktion, Computerstatik, FEM, Computergestützte Graphostatik und Historische Technikwissenschaft. Gegenüber der 1., englischen Ausgabe wurde der Seitenumfang um 50 % auf nunmehr etwas über 1200 Druckseiten gesteigert. Das vorliegende Buch ist die erste zusammenfassende historische Gesamtdarstellung der Baustatik vom 16. Jahrhundert bis heute. Über die Reihe edition Bautechnikgeschichte: Mit erstaunlicher Dynamik hat sich die Bautechnikgeschichte in den vergangenen Jahrzehnten zu einer höchst lebendigen, international vernetzten und viel beachteten eigenständigen Disziplin entwickelt. Auch wenn die nationalen Forschungszugänge unterschiedliche Akzente setzen, eint sie doch das Bewusstsein, dass gerade die inhaltliche und methodische Vielfalt und das damit verbundene synthetische Potenzial die Stärke des neuen Forschungsfeldes ausmachen. Bautechnikgeschichte erschließt neue Formen des Verstehens von Bauen zwischen Ingenieurwesen und Architektur, zwischen Bau- und Kunst-, Technik- und Wissenschaftsgeschichte. Mit der edition Bautechnikgeschichte erhält die neue Disziplin erstmals einen Ort für die Publikation wichtiger Arbeiten auf angemessenem Niveau in hochwertiger Gestaltung. Die Bücher erscheinen in deutscher oder englischer Sprache. Beide Hauptrichtungen der Bautechnikgeschichte, der eher konstruktionsgeschichtlich und der eher theoriegeschichtlich geleitete Zugang, finden Berücksichtigung; das Spektrum der Bände reicht von Überblickswerken über Monographien zu Einzelaspekten oder -bauten bis hin zu Biographien bedeutender Ingenieurpersönlichkeiten. Ein international besetzter Wissenschaftlicher Beirat unterstützt die Herausgeber in der Umsetzung des Konzepts.

Book Synopsis Railway Management and Engineering by : V Profillidis
Download or read book Railway Management and Engineering written by V Profillidis and published by Routledge. This book was released on 2016-12-05 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a rapidly changing world, with increasing competition in all sectors of transportation, railways are in a period of restructuring their management and technology. New methods of organization are introduced, commercial and tariff policies change radically, a more entrepreneurial spirit is required. At the same time, new high-speed tracks are being constructed and old tracks are renewed, high-comfort rolling stock vehicles are being introduced, logistics and combined transport are being developed. Awareness of environmental issues and the search for greater safety give a new role to the railways within the transportation system. Meanwhile, methods of analysis have significantly evolved, principally due to computer applications and new ways of thinking and approaching old problems. Thus, it becomes necessary to come up with a new scientific approach to tackle management and engineering aspects of railways, to understand in-depth the origins and inter-relationships of the various situations and phenomena and to suggest the appropriate methods and solutions to solve the various emerging problems. This book aims to cover the need for a new scientific approach for railways. It is intended to be of use to railway managers, economists and engineers, consulting economists and engineers, students of schools of engineering, transportation, economics, and management. The book is divided into three parts, which deal successively with management, track, and rolling stock, environment and safety. Each chapter of the book contains the necessary theoretical analysis of the phenomena studied, the recommended solutions, applications, charts and design of the specific railway component. In this way, both the requirement for a theoretical analysis is met, and the need of the railway manager and engineer for tables, nomographs, regulations, etc. is satisfied. Railways in Europe have separated activities of infrastructure from those of operation. In other parts of the world, however, railways remain unified. The book addresses both situations (separated and unified railways). Railways present great differences in their technologies. Something may be valid for one such technology, but not for another. To overcome this problem, regulations of the International Union of Railways (UIC) as well as European Standardization (CEN) and European Technical Specifications for Interoperability (TSIs) have been used to the greatest extent possible. Whenever a specific technology or method is presented, the limits of its application are clearly emphasized.
Book Synopsis Comptes Rendus Du 15ème Congrès Européen de Mécanique Des Sols & de Géotechnique : la Géotechnique Des Sols Indurés, Roches Tendres by : Andreas Anagnostopoulos
Download or read book Comptes Rendus Du 15ème Congrès Européen de Mécanique Des Sols & de Géotechnique : la Géotechnique Des Sols Indurés, Roches Tendres written by Andreas Anagnostopoulos and published by IOS Press. This book was released on 2013 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains the papers presented at the 15th European Conference on Soil Mechanics and Geotechnical Engineering (ECSMGE), held in Athens, Greece. Considerable progress has been made in recent decades in understanding the engineering behavior of those hard soils and weak rocks that clearly fall into either the field of soil or of rock mechanics, and there have been important developments in design and construction methods to cope with them. Progress would be even more desirable, however, for those materials which fall into the 'grey' area between soils and rocks. They present particular challenges due to their diversity, the difficulties and problems arising in their identification and classification, their sampling and testing and in the establishment of suitable models to adequately describe their behavior. The publication aims to provide an updated overview of the existing worldwide knowledge of the geological features, engineering properties and behavior of such hard soils and weak rocks, with particular reference to the design and construction methods and problems associated with these materials. Part 4 was published post-conference and includes Conference Reports.
Book Synopsis Entre Mécanique et Architecture / Between Mechanics and Architecture by : Patricia Radelet-de Grave
Download or read book Entre Mécanique et Architecture / Between Mechanics and Architecture written by Patricia Radelet-de Grave and published by Birkhäuser. This book was released on 2012-12-06 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collective work and its richness lies in the diversity of the perspectives, all historical, focussed on the science of building. Its aim is to counter-balance the picture of architecture provided by art historians who, in general, study the evolution of buildings. In this book, the authors look into what is related to the actual act of building, to the means of assuring building stability. While historians of art are principally concerned with the esthetics of a monument, here the accent is put on the development of the physico- mathematical theories of mechanics to which engineers and constructors have turned, and to the laws of mechanics, of elasticity and of the strength of materials to which they are bound. The study of perspective and projective geometry also enters the work by way of the representations and plans of the buildings to be constructed. The art of building has always been at the center of human endeavors, and the will to see this art advance has had repercussions in all related fields. Today, these complex interrelations provide the groundwork for research of the restoration of historical monuments.
Book Synopsis Mastering Calculations in Linear and Nonlinear Mechanics by : Pierre Ladevèze
Download or read book Mastering Calculations in Linear and Nonlinear Mechanics written by Pierre Ladevèze and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the management of calculations in linear and nonlinear mechanics. Particular attention is given to error estimators and indicators for structural analysis. The accent is on the concept of error in constitutive relation. An important part of the work is also devoted to the utilization of the error estimators involved in a calculation, beginning with the parameters related to the mesh. Many of the topics are taken from the most recent research by the authors: local error estimators, extention of the concept of error in constitutive relation to nonlinear evolution problems and dynamic problems, adaptive improvement of calculations in nonlinear mechanics. This work is intended for all those interested in mechanics: students, researchers and engineers concerned with the construction of models as well as their simulation for industrial purposes.

Available in PDF, EPUB and Kindle. Book excerpt: In a rapidly changing world, with increasing competition in all sectors of transportation, railways are currently restructuring their planning, management, and technology. As commercial and pricing policies change and new methods of organization are introduced, a more entrepreneurial spirit is required. At the same time, new high-speed tracks are being constructed and old tracks are being renewed, magnetic levitation trains are in operation, hyperloop systems are being planned, high-comfort rolling stock vehicles are being introduced, logistics and combined transport are being developed. Awareness of environmental issues and the search for greater safety attribute a new role to the railways within the transportation system. Meanwhile, methods of analysis have evolved significantly, principally due to computer applications, the internet revolution, satellite technologies, and artificial intelligence, all of which offer new ways of thinking about and addressing old problems. Railway Planning, Management, and Engineering aims to fulfill the need for a new scientific approach for railways. It is intended to be of use to railway planners, managers, economists, engineers, and students in engineering, transportation, economics, and management. The book is divided into three parts, which deal successively with planning, management, track, rolling stock, safety, and the environment.

Available in PDF, EPUB and Kindle. Book excerpt: The International Conference on Mechanical Design and Production has over the years established itself as an excellent forum for the exchange of ideas in these established fields. The first of these conferences was held in 1979. The seventh, and most recent, conference in the series was held in Cairo during February 15-17, 2000. International engineers and scientists gathered to exchange experiences and highlight the state-of-the-art research in the fields of mechanical design and production. In addition a heavy emphasis was placed on the issue of technology transfer. Over 100 papers were accepted for presentation at the conference. Current Advances in Mechanical Design & Production VII does not, however, attempt to publish the complete work presented but instead offers a sample that represents the quality and breadth of both the work and the conference. Ten invited papers and 54 ordinary papers have been selected for inclusion in these proceedings. They cover a range of basic and applied topics that can be classified into six main categories: System Dynamics, Solid Mechanics, Material Science, Manufacturing Processes, Design and Tribology, and Industrial Engineering and its Applications.
