This electronic book, by engineer and teacher David Pintur, is an thoroughly illustrated introduction to the principles of the finite element method. If you use, or intend to use, existing finite element packages but want a firm theoretical understanding of the methodology, this book is ideal. Through a variety of examples, you get a solid foundation for establishing finite element applications so you can move on to more advanced programs. Items covered include selecting interpolation functions, assembling stiffness matrices, and solving for field variables at each node.
Emphasis is given to the areas of structural analysis and boundary value problems.
Each step of the method is implemented with live Mathcad calculations and plots, allowing the user to explore and experiment with the method interactively. In addition, a generalized finite element code is presented for applications outside of the structural analysis arena. This book bridges the gap between the theory of differential equations and its application to realistic common engineering problems. With the aid of beautiful graphics and lost of clear and concise text, the reader is pleasurably led from beginning to end. The electronic book is a great accompaniment to graduate or senior level courses and an indispensable tool to the working scientist and engineer.
