From the above discussion, it is observed that FDM is simple and easy to implement, but difficult to implement for irregular geometry problems.

BEM has some specific advantages over FEM, such as reduction in computational dimension and ease in handling of data. Choice of the method is largely governed by the complexity of the problem, geometry, investigator's familiarity of the method and other factors such as availability of particular packages, computational facilities and so on. This book deals with the theory and practice of the well-established FEM.

In the pre-processing part of the model, input required to solve the problem are generated or read in. Input data required include domain geometry, initial and boundary conditions, coefficients and constants for the particular problem, value of universal constants, the grid information finite difference grid, finite element mesh or boundary element mesh and various options for the concerned problem such as one-, two- or three-dimensional analysis; steady state or transient analysis.

In the processing part, real simulation of the problem with the concerned numerical model is done.

For example, processing in the context of FEM includes generation of element matrices, assembly of element equations, and imposition of boundary conditions and solution of system of equations. In the post-processing part, results obtained are processed in terms of tables, charts, graphs, contours, bar chart and so on. Mesh generation is an important task of pre-processing.

Mesh or grid generation includes discretization of the concerned domain into elements or cells and determining grid points or nodal positions. Subsequently, nodes and elements are numbered and nodal positions and connectivity between elements are specified such that the processor can identify the problem domain, discretization and nodal position.

Mesh or grid generation depends on the type of numerical model used and dimension of the model.

On the other hand, such process is easier when BEM is used. Mesh or grid can be generated manually 16 Finite Element Method with Applications in Engineering or through computer models.

For automatic mesh generation, computer programs can be written and incorporated in the model itself or separate mesh generating packages can be utilized. Figure 1. It is thus better to present 17 Finite Element Method with Applications in Engineering such details either graphically or in tabular forms. Graphical display may include deformed shape of mesh, vectors, charts, contours, and so on. The post-processing can be done manually or through computer models.

For post-processing, computer program can be written such that results are displayed graphically or separate post-processing packages can be used. The main emphasis is given to important applications in engineering and science.

An effort has been made to keep the mathematics simple. Since majority of applications of FEM are in the realm of mechanics including solid, fluids, structural and soil, descriptions in this book are primarily in terms of these fields of study. To effectively use the book, necessary pre-requisites are relatively moderate such as understanding of basic mechanics and physics, basic courses in advanced calculus and linear algebra and basic concepts of various engineering theories.

For effective study and application of FEM, the reader must have working capability in several fundamental areas such as matrices, algebra, calculus and basic computer skills. The reader is assumed to have these backgrounds. However, to make the text as self-contained as possible, a brief description of these topics are given in appendices.

An overview of various approximate methods of analyses has been presented in Chapter 2wherein the basics of FEM have been evolved. An introduction to FEM with history, applications, merits and demerits are detailed in Chapter 3.

Important approaches in FEM have been described in Chapter 4. Interpolation functions used in FEM are explained in Chapter 5. Detailed formulation and applications of FEM in one-dimensional for various engineering problems are presented in Chapter 6. Formulation, implementation and applications of FEM in two-dimensional are elaborated in Chapter 7. Three-dimensional formulations of some engineering problems are presented in Chapter 8. Details of the computer implementation of FEM with details of intuitive, teaching purpose program are given in Chapter 9.

Further advanced level of FEM formulation and applications are described in Chapter Various FEM software and web resources available are also discussed in this chapter.

Brief review of matrix algebra and calculus, elements of calculus of variation, illustration on use of Galerkin's method, review of Gauss quadrature procedure for numerical integration, user's manual for the simplified finite element analysis program SFEAP , further illustrative one- and two-dimensional computer programs are detailed in various appendices.

One may take a physical or intuitive approach to learning of FEM. On the other hand, one may develop a rigorous mathematical interpretation of the method. A middle path has been adopted in this book giving more importance to the physical approach, with essential mathematical basis. The book can be used for basic understanding of FEM by beginners, further understanding by FEM practitioners and to certain extent for the advanced level understanding of researchers. For the benefit of beginners, explanation of FEM with basic theories and fundamental applications in structural, geo- and fluid-mechanics are presented in one-, two- and three-dimensional domains.

Once the basic concepts of FEM are understood with illustrative examples, one can study advanced topics and apply the method to complex problems and to other areas. The book is written in a simple structured way starting with the basics of various FEM approaches, description of finite element interpolation functions, FEM formulations and applications in one-, two- and three-dimensional domains and further advanced applications for more complex problems.

The book is intended as an introduction to FEM as well as oriented towards various applications in engineering and science. It is envisaged that several practical applications and examples presented in the book will enable an engineer to assess the potential of FEM and its applicability to specific engineering problems.

Various exercise problems are also proposed in the book. Further, the important FEM software and Web resources available for solution of various engineering and science related problems are briefly discussed. Emphasis of the book is on development of FEM formulation and implementation of the method to various problems. A very illustrative and simple computer program SFEAP with sophisticated graphical user interface for pre-processing and post-processing are given for structural and solid mechanics related problems.

These programs can be operated on desktop PCs. Source codes of these programs are also given so that the reader can easily understand the computer implementation of the method. These codes not only demonstrate the implementation of the methods described in the book, but also help readers who are contemplating in preparing their own computer codes. A large number of books are available on FEM. Thus, it may be rather difficult for a user student, teacher or practitioner to effectively follow-up a plan-of-study.

Of course, the plan-of-study may depend on the time available and the objectives of the study such as 1. To study the FEM systematically for the solution of complex problems students and teachers.

To study FEM for minimum understanding to use software for practical design and analysis problems practitioners. This book has been written primarily to serve the first objective. However, it addresses the other two objectives also.

To meet the first objective for students and teachers, the FEM has been presented systematically from the basics to one-, two- and three-dimensional applications.

Users may study all chapters systematically from Chapters 2 through For researchers or advanced learners, in addition to the systematic approach, some advanced level topics have been presented in Chapter For FEM practitioners, in addition to understanding of basics of FEM, the book is presented with software with pre- and post-processing graphical user interface, which can be used in practical application of problems and get training.

Depending on the interest, to meet the third objective, users may concentrate on Chapters 3, 6, 7, 8and 9. This book has not been written to provide a broad survey of FEM as it may require much more comprehensive volumes. The book has concentrated on more commonly used and 19 Finite Element Method with Applications in Engineering effective FEM techniques that can be applied to engineering problems.

It is important, however, that good judgement be developed and exercised concerning the solution of any complex engineering problem to achieve the desired results using FEM. To achieve this, the analyst must be sufficiently familiar with possible available finite element procedure and models. In this direction, the SFEAP software provided with this book will provide sufficient background of learning and in reinforcing the understanding of FEM. Detailed procedures of mathematical modelling are illustrated, which are directly applicable to most engineering problems.

Modelling methodology may vary. However, procedure more or less remains unchanged. Further, various types of mathematical equations and boundary conditions used in modelling are discussed.

Accurate results can be obtained only if the mathematical model developed is appropriate. Various analyses and solution methodologies for modelling are further illustrated in the subsequent chapters.

Since a few analytical solutions are possible for simplified problems and the physical modelling is quite cumbersome and expensive, most engineering problems are solved using numerical methods such as FDM, FVM, FEM and BEM. Various aspects of pre-processing and post-processing are also discussed briefly in the context of various numerical methods.

FEM is elaborated in the subsequent chapters. Aris, R. Mathematical Modeling Techniques, Pitman, London. Beer, G. They supply practical information on boundary conditions and mesh generation, and they offer a fresh perspective on finite element analysis with an overview of the current state of finite element optimal design. Supplemented with numerous real-world problems and examples taken directly from the authors' experience in industry and research, The Finite Element Method for Engineers, Fourth Edition gives readers the real insight needed to apply the method to challenging problems and to reason out solutions that cannot be found in any textbook.
