This book provides a relatively simple, but complete, approach to finite element (FE) theory and applications. It is written specifically for engineers and scientists who want to understand the fundamental theory of FE analysis and to learn how to analyze practical problems using FE software. The prerequisite knowledge required for the readers is a basic understanding of engineering mechanics and mathematics covered in engineering undergraduate courses. No prior knowledge of FE theory of FE software packages is assumed. Because of the complexity of finite element analysis, this book is particularly useful for young engineers, who would benefit from a practical, introductory guide on the topic. It is also suitable as a refresher and handy reference for more senior engineers. Includes a four-page section of full-color diagrams.
