Finite Elemente Modelle der Maschinenelemente
by Klaus SchierIn diesem Buch wird eine Auswahl von Maschinenelementen zu Finite-Elemente-Modellen aufbereitet. Die Abläufe der Modellbildung sind durch Text- und Bildfolgen dokumentiert und so allgemein gehalten, dass keine Abhängigkeiten zu einem bestimmten FE-System bestehen. Jedes Modell wird durch eine Berechnung nach klassischer Berechnungsmethode verifiziert und diskutiert. Varianten des Lösungsansatzes werden herausgestellt. Es wird auf eine praxisorientierte Beschreibung geachtet. Der Inhalt des Buches ist klar gegliedert. CAE-Techniken enthalten Konstruieren (CAD), Berechnen und Optimieren (FEM). Das Berechnen kann überschläglich erfolgen, zu bestimmten Themen auch tiefgründiger nach klassischen Theorien und Berechnungsprogrammen. Es sind aber erkennbare Grenzen gesetzt. Bei der Berechnung von Maschinenelementen müssen häufig Mittelwerte angenommen werden. Damit wird das Optimieren eingeschränkt. Das Berechnungswerkzeug „Finite Elemente Methode (FEM)" schließt diese Lücke.
Finite Elemente Modelle der Statik und Festigkeitslehre: 101 Anwendungsfälle zur Modellbildung
by Klaus SchierUm die Finite Elemente Methode (FEM) bei anspruchsvollen Aufgaben anwenden zu können, werden Softwaresysteme benötigt. Die Modellbildung rückt damit in den Mittelpunkt der Problemlösung. Der Band vermittelt nach einer kurzen Einführung in die FE-Methode die Abläufe der Modellbildung in allgemeiner Form, das heißt, unabhängig von bestimmten FEM-Programmen. Im Zentrum stehen die Modellbildung an Tragwerken, an Bauteilen bei unterschiedlichen Beanspruchungsarten, die Anwendung verschiedener Elementtypen sowie die Verifizierung der FE-Ergebnisse.
Finite Elemente Programme für Platten und Schalen
by E. Hinton D. R. J. Owen Gerhard KrauseDas Buch geht über die Beschreibung der Methode oder spezieller Programme weit hinaus: Es bietet einen relativ einfachen Zugang, indem lediglich geringe mathematische Vorkenntnisse (Differentialgleichungen und Matrizenrechnung) erwartet und die Voraussetzungen der schubweichen Plattentheorie und einer speziellen Schalentheorie so weit dargestellt werden, wie man sie zum Aufstellen der finiten Gleichungen benötigt. Die hergeleiteten Bezeichnungen sind nicht nur relativ leicht nachvollziehbar, sondern werden in Form von Programmen praktisch vermittelt; die Umsetzung wird an praxisorientierten Beispielen demonstriert. Die Programme können dazu dienen, sie auf eigene Probleme anzuwenden, die Software weiter auszubauen oder aber verfeinerte Algorithmen zu implementieren. Diese Ausgabe ist gegenüber dem englischen Original erweitert und aktualisiert worden.

Finite Elements: A Gentle Introduction
by J. Bonet D.J. HenwoodThe finite element method is popular among engineers and scientists as a numerical technique for solving practical problems. At the same time, the links with classical variational methods make the technique of interest to mathematicians. This book introduces the main concepts of the finite element method in a simple and carefully paced manner, using numerical examples wherever possible. Both the theoretical and practical aspects are described and explained. A basic knowledge of engineering mathematics is all that is required, and the style is not formal. The approach and treatment are intended to appeal to the advanced undergraduate or postgraduate, or to the practising engineer who wishes to acquire a deeper understanding of the finite element software that he is using.

by D. L. Dwoyer M. Y. Hussaini R. G. VoigtThis volume covers the proceedings ofthe ICASE/LaRC workshop on "Finite Element Theory and Application" held during July 28-30, 1986. The purpose of this workshop was to provide an update on the status of finite element theory, to assess the impactoftbis theory on practice, and to suggest directions for Cuture research. There were thirteen participants in the workshop. Some of them were leading mathematicians working on the finite element theory, and the rest expert practitioners in the areas of fluid dynamics and structural analysis. The first six articles in this volume provide a brief review of the theoretical and computational aspects of finite element methods (FEM). The remaining seven articles deal with a variety of applications highlighting the type of results that are possible, and indicating areas which deserve future research. The first article is by Temam. lt provides an introduction and overview of the general finite element methods for the nonspecialist. lt also illustrates the power of finite element methods with two specific applications-the free surface flowjstructure interaction problern and the compressible Euler solu tion to the flow past a finite aspect ratio flat plate at incidence. The second article by Brezzi is againan introduction and overview ofmixed finite element methods. lt includes a brief discussion of special techniques for solving the discrete problem, as weil as some applications to certain basic problems in elasticity and hydrodynamics.

Finite Elements for Truss and Frame Structures: An Introduction Based on the Computer Algebra System Maxima (SpringerBriefs in Applied Sciences and Technology)
by Andreas Öchsner Resam MakvandiThis book is intended as an essential study aid for the finite element method. Based on the free computer algebra system Maxima, the authors offer routines for symbolically or numerically solving problems in the context of plane truss and frame structures, allowing readers to check classical ‘hand calculations’ on the one hand and to understand the computer implementation of the method on the other. The mechanical theories focus on the classical one-dimensional structural elements, i.e. bars, Euler–Bernoulli and Timoshenko beams, and their combination to generalized beam elements. Focusing on one-dimensional elements reduces the complexity of the mathematical framework, and the resulting matrix equations can be displayed with all components and not merely in the form of a symbolic representation. In addition, the use of a computer algebra system and the incorporated functions, e.g. for equation solving, allows readers to focus more on the methodology of the finite element method and not on standard procedures.

Finite Elements in Fracture Mechanics: Theory - Numerics - Applications (Solid Mechanics and Its Applications #201)
by Meinhard KunaFracture mechanics has established itself as an important discipline of growing interest to those working to assess the safety, reliability and service life of engineering structures and materials. In order to calculate the loading situation at cracks and defects, nowadays numerical techniques like finite element method (FEM) have become indispensable tools for a broad range of applications. The present monograph provides an introduction to the essential concepts of fracture mechanics, its main goal being to procure the special techniques for FEM analysis of crack problems, which have to date only been mastered by experts. All kinds of static, dynamic and fatigue fracture problems are treated in two- and three-dimensional elastic and plastic structural components. The usage of the various solution techniques is demonstrated by means of sample problems selected from practical engineering case studies. The primary target group includes graduate students, researchers in academia and engineers in practice.

Finite Elements in Water Resources: Proceedings of the 4th International Conference, Hannover, Germany, June 1982
by K. P. Holz U. Meissner W. Zielke C. A. Brebbia G. Pinder W. GrayThese proceedings contain the papers presented at the Fourth International Conference on Finite Elements in Water Resources, held in June, 1982, at the University of Hannover, Federal Re public of Germany. This Conference continued the successful series of previous conferences held at Princeton University in 1976, at Imperial College in 1978, and at the University of Mississippi in 1980. Since Finite Elements have proved to be a powerful means for analysing water resource problems, the principal objective of the Conference was to provide an exchange of experiences in practical applications of the finite element method and to establish a forum for discussion regarding accuracy, economy, limitations and improvements. Related discretization methods were included within the scope of the Conference. New develop ments in numerical and computational techniques, basic mathe matical formulations, and soft- and hardware aspects were considered to be equally important topics for an exchange of ideas between both theoretically and practically oriented re searchers. The Conference Organizing Committee is very grateful to the many distinguished scientists who attended the Conference, and for their contributions towards the proceedings. This collection of papers in being made available to a wider audience of en gineers and scientists by CML Publications in Southampton, U.K.
