Developed from the authors, combined total of 50 years
undergraduate and graduate teaching experience, this book presents
the finite element method formulated as a general-purpose numerical
procedure for solving engineering problems governed by partial
differential equations.
Focusing on the formulation and application of the finite element
method through the integration of finite element theory, code
development, and software application, the book is both
introductory and self-contained, as well as being a hands-on
experience for any student.
This authoritative text on Finite Elements:
* Adopts a generic approach to the subject, and is not application
specific
* In conjunction with a web-based chapter, it integrates code
development, theory, and application in one book
* Provides an accompanying Web site that includes ABAQUS Student
Edition, Matlab data and programs, and instructor resources
* Contains a comprehensive set of homework problems at the end of
each chapter
* Produces a practical, meaningful course for both lecturers,
planning a finite element module, and for students using the text
in private study.
* Accompanied by a book companion website housing supplementary
material that can be found at
http://www.wileyeurope.com/college/Fish
A First Course in Finite Elements is the ideal practical
introductory course for junior and senior undergraduate students
from a variety of science and engineering disciplines. The
accompanying advanced topics at the end of each chapter also make
it suitable for courses at graduate level, as well as for
practitioners who need to attain or refresh their knowledge of
finite elements through private study.

The text material evolved from over 50 years of combined teaching experience it deals with a formulation and application of the finite element method. A meaningful course can be constructed from a subset of the chapters in this book for a quarter course; instructions for such use are given in the preface. The course material is organized in three chronological units of one month each: 1) the finite element formulation for one-dimensional problems, 2) the finite element formulation for scalar field problems in two dimensions and 3) finite element programming and application to scalar field problems; and finite element formulation for vector field problems in two dimensions and beams. In conjunction with the book there will be the access and use of ABAQUS software and MATLAB exercises.
