Since the appearance of the first edition 38 years ago, The Finite Element Method provides arguably the most authoritative introductory text to the method, covering the latest developments and approaches in this dynamic subject, and is amply supplemented by exercises, worked solutions and computer algorithms.• The classic FEM text, written by the subject's leading authors • Enhancements include more worked examples and exercises• With a new chapter on automatic mesh generation and added materials on shape function development and the use of higher order elements in solving elasticity and field problemsActive research has shaped The Finite Element Method into the pre-eminent tool for the modelling of physical systems. It maintains the comprehensive style of earlier editions, while presenting the systematic development for the solution of problems modelled by linear differential equations. Together with the second and third self-contained volumes (0750663219 and 0750663227), The Finite Element Method Set (0750664312) provides a formidable resource covering the theory and the application of FEM, including the basis of the method, its application to advanced solid and structural mechanics and to computational fluid dynamics. - The classic introduction to the finite element method, by two of the subject's leading authors - Any professional or student of engineering involved in understanding the computational modelling of physical systems will inevitably use the techniques in this key text

Available in PDF, EPUB and Kindle. Book excerpt: Este trabalho apresenta algoritmos de geração automática de malhas de elementos finitos bidimensionais e tridimensionais que, juntamente com outros algoritmos desenvolvidos dentro da linha de pesquisa ao qual ele está inserido, são integrados consistentemente em um pacote computacional. Os algoritmos geradores de malhas foram modificados para serem independentes dos pré-processadores, podendo assim serem incorporados em diferentes programas. Um novo algoritmo bidimensional de geração de elementos triangulares é proposto. Este algoritmo incorpora novas idéias, adaptadas de um algoritmo de geração tridimensional de malhas em volume arbitrário, e procura gerar elementos de melhor qualidade geométrica possível. Duas técnicas de geração de malhas sólidas são apresentadas: uma de mapeamento transfinito tridimensional, onde a malha sólida é construída a partir das seções transversais do modelo; e uma técnica de sweep, onde a malha sólida é construída pelo arrasto de uma seção transversal ao longo de um curva no espaço. Os algoritmos são incorporados em um modelador geométrico tridimensional, o MG (Mesh Generator), e alguns exemplos são feitos para demonstrar a capacidade de modelagem do ambiente criado. Em particular são mostrados exemplos para modelagem composta com diferentes métodos de construção de malhas e diferentes tipos de elementos finitos em um mesmo modelo. Também é feito um estudo de algumas medidas de distorção para elementos finitos planos. O cálculo dessas medidas de distorção é implementado em um modelador bidimensional gráfico interativo. A visualização das medidas de distorção é feita através de uma escala de cores.

Download or read book Probabilities and Materials written by D. Breysse and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most industrial and natural materials exhibit a macroscopic behaviour which results from the existence of microscale inhomogeneities. The influence of such inhomogeneities is commonly modelled using probabilistic methods. Most of the approaches to the evaluation of the safety of structures according to probabilistic criteria are somewhat scattered, however, and it is time to present such material in a coherent and up-to-date form. Probabilities and Materials undertakes this task, and also defines the great tasks that must be tackled in coming years. For engineers and researchers dealing with materials, geotechnics, solid mechanics, soil mechanics, statistics and stochastic processes. The expository nature of the book means that no prior knowledge of statistics or probability is required of the reader. The book can thus serve as an excellent introduction to the nature of applied statistics and stochastic modelling.
Download or read book Transfinite Mappings and Their Application to Grid Generation written by and published by . This book was released on 1982 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The two essential ingredients of any boundary value problem are the field equations which describe the physics of the problem and a set of relations which specify the geometry of the problem domain. Mesh generations or grid generators are preprocessors which decompose the problem domain into a large number of interconnected finite elements or curvilinear finite difference stencils. A number of such techniques have been developed over the pat decade to alleviate the frustration and reduce the time involved in the tedious manual subdividing of a complex-shaped region or 3-D structure into finite elements. Our purpose here is to describe how the techniques of bivariate and trivariate blending function interpolation, which were originally developed for and applied to geometric problems of computer-aided design of sculptured surfaces and 3-D solids, can be adapted and applied to the geometric problems of grid generation. In contrast to other techniques which require the numerical solution of complex partial differential equations (and, hence, a great deal of computing), the transfinite methods proposed herein are computationally inexpensive.

Fluid Dynamics Panel. Specialists' Meeting and published by . This book was released on 1990 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AGARD Fluid Dynamics Panel sponsored this Symposium to provide a survey of the capabilities of the CFD community for griding complex 3-D configurations. The intent was to provide some insight to the present state of grid generation for complex configurations to help assess whether this task presents a long-term stumbling block to the routine use of CFD in aerodynamic applications. To this end, the meeting was structured in five sessions: General Surveys, Algebraic Grid Generation, Block Structured Meshes, Multiblock-Adaptive Meshes and Unstructured Meshes. Thwenty-two papers from these sessions amply gemonstrated that the viability of a numerical solution depends directly on the quality of the mesh and surface representation as measured by its spacing and resolution. Of Particular interest was the mesh generation for complex configurations, such as advanced fighter or transport aircraft, missiles and space vehicles, where complex geometries and/or complex flowfields have to be analysed. Results from this meeting indicate that geometry discretization and generation of meshes for complex 3-D configurations in aerospace will continue to be time- and cost-consuming operations fro some time to come.

Available in PDF, EPUB and Kindle. Book excerpt: Highlights the Progression of Meshing Technologies and Their Applications Finite Element Mesh Generation provides a concise and comprehensive guide to the application of finite element mesh generation over 2D domains, curved surfaces, and 3D space. Organised according to the geometry and dimension of the problem domains, it develops from the basic meshing algorithms to the most advanced schemes to deal with problems with specific requirements such as boundary conformity, adaptive and anisotropic elements, shape qualities, and mesh optimization. It sets out the fundamentals of popular techniques, including: Delaunay triangulation Advancing-front (ADF) approach Quadtree/Octree techniques Refinement and optimization-based strategies From the geometrical and the topological aspects and their associated operations and inter-relationships, each approach is vividly described and illustrated with examples. Beyond the algorithms, the book also explores the practice of using metric tensor and surface curvatures for generating anisotropic meshes on parametric space. It presents results from research including 3D anisotropic meshing, mesh generation over unbounded domains, meshing by means of intersection, re-meshing by Delaunay-ADF approach, mesh refinement and optimization, generation of hexahedral meshes, and large scale and parallel meshing, along with innovative unpublished meshing methods. The author provides illustrations of major meshing algorithms, pseudo codes, and programming codes in C++ or FORTRAN. Geared toward research centers, universities, and engineering companies, Finite Element Mesh Generation describes mesh generation methods and fundamental techniques, and also serves as a valuable reference for laymen and experts alike.
