Finite element analysis has become the most popular technique for studying engineering structures in detail. It is particularly useful whenever the complexity of the geometry or of the loading is such that alternative methods are inappropriate. The finite element method is based on the premise that a complex structure can be broken down into finitely many smaller pieces (elements), the behaviour of each of which is known or can be postulated. These elements might then be assembled in some sense to model the behaviour of the structure. Intuitively this premise seems reasonable, but there are many important questions that need to be answered. In order to answer them it is necessary to apply a degree of mathematical rigour to the development of finite element techniques. The approach that will be taken in this book is to develop the fundamental ideas and methodologies based on an intuitive engineering approach, and then to support them with appropriate mathematical proofs where necessary. It will rapidly become clear that the finite element method is an extremely powerful tool for the analysis of structures (and for other field problems), but that the volume of calculations required to solve all but the most trivial of them is such that the assistance of a computer is necessary. As stated above, many questions arise concerning finite element analysis. Some of these questions are associated with the fundamental mathematical formulations, some with numerical solution techniques, and others with the practical application of the method. In order to answer these questions, the engineer/analyst needs to understand both the nature and limitations of the finite element approximation and the fundamental behaviour of the structure. Misapplication of finite element analysis programs is most likely to arise when the analyst is ignorant of engineering phenomena.

Designing structures using composite materials poses unique challenges due especially to the need for concurrent design of both material and structure. Students are faced with two options: textbooks that teach the theory of advanced mechanics of composites, but lack computational examples of advanced analysis; and books on finite element analysis that may or may not demonstrate very limited applications to composites. But now there is third option that makes the other two obsolete: Ever J. Barbero's Finite Element Analysis of Composite Materials. By layering detailed theoretical and conceptual discussions with fully developed examples, this text supplies the missing link between theory and implementation. In-depth discussions cover all of the major aspects of advanced analysis, including three-dimensional effects, viscoelasticity, edge effects, elastic instability, damage, and delamination. More than 50 complete examples using mainly ANSYSTM, but also including some use of MATLAB®, demonstrate how to use the concepts to formulate and execute finite element analyses and how to interpret the results in engineering terms. Additionally, the source code for each example is available for download online. Cementing applied computational and analytical experience to a firm foundation of basic concepts and theory, Finite Element Analysis of Composite Materials offers a modern, practical, and versatile classroom tool for today's engineering classroom.

Die vorliegende Sammlung von Unterprogrammen und Hauptprogrammen zur Methode der finiten Elemente soll Studierenden und bereits in der Praxis tätigen Leuten als Ergänzung zum Lehrbuch [Sch91] ein nützliches und zugleich anregendes Hilfsmittel sein. Einerseits will ich dem praktisch orientierten Studierenden einen Einblick in die im Lehrbuch skizzierten Techniken einer Implementierung auf einem Rechner ver mitteln. Anderseits soll ihm die angebotene Sammlung von Programmen die Lösung von konkreten, ihn speziell interessierenden Aufgaben mit Hilfe eines Personal Computers ermöglichen oder zumindest erleichtern. Der Aufbau der publizierten Programme ist bewusst so einfach gestaltet worden, dass die Prinzipien leicht erkannt werden sollten und dass analoge Rechenprogramme für nicht berücksichtigte Fälle und Kombinationen ohne grosse Schwierigkeiten und mit relativ kleinem Aufwand ent wickelt werden können. Der prinzipielle Aufbau eines Programmpaketes zur Lösung einer konkreten Aufgabe ist durch die Methode der finiten Elemente im wesentlichen bereits vorgezeichnet. Die Programmsammlung folgt deshalb weitgehend der Gliederung von [Sch91]. So sind im zweiten Kapitel die Unterprogramme zur Bereitstellung der Elementmatrizen für die ein schlägigen Elemente zusammengestellt. Das dritte Kapitel enthält eine Auswahl von Unterprogrammen zur Kompilation der Gesamtmatrizen sowohl für statische Probleme als auch für Schwingungsaufgaben. Die Unterprogramme wurden unter dem Aspekt so ausgewählt, dass die Speicherungsarten für die Gesamtmatrizen in Bandform, zwei Arten der Hüllenform und in kompakter zeilenweiser Form Anwendung finden und dass verschiedene Varianten für einen effizienten Aufbau dargestellt werden können.

Finite Element Simulations Using ANSYS

The complexity of modern-day problems in mechanical engineering makes relying on pure theory or pure experiment impractical at best and time-consuming and unwieldy at worst. And for a large class of engineering problems writing computer codes from scratch is seldom found in practice. Use of reputable, trustworthy software can save time, effort, and resources while still providing reliable results. Finite Elements Simulations Using ANSYS focuses on the application of this design software in solving practical engineering problems. The book presents fundamental knowledge of numerical simulation using ANSYS. It covers all disciplines in mechanical engineering: structure, solid mechanics, vibration, heat transfer, and fluid dynamics, with adequate background material to explain the physics behind the computations. The author treats each physical phenomenon independently, enabling readers to single out subjects or related chapters and study them as self-contained units. Because a finite element solution is greatly affected by the quality of the mesh, a separate chapter on mesh generation is included as a simple meshing guide, emphasizing the basics. Each chapter contains a number of pictorially guided problems with appropriate screenshots that provide a step-by-step, easy-to-follow technical demonstration. The book includes end-of-chapter problems, several practical, open-ended case studies, and a number of complete tutorials on using ANSYS to resolve the issues engineers tackle on a regular basis. Instructors can liberally select appropriate chapters to be covered depending on the objectives of the course. The author first explains multiphysics analyses, such as structure-thermal or fluid-thermal analyses, in terms of theory, then derives the equations governing the physical phenomena and presents modeling techniques. Many of the sample problems, questions, and solved examples were used in CAD courses in many universities around the world. They cover structural analysis, solid mechanics and vibration, steady-state and transient heat-transfer analysis, fluid dynamics, multiphysics simulations, and modeling and meshing. Written and organized so that it can easily be used for self-study, this book guides readers through the basic modeling requirements to the correct and physically meaningful numerical result.
