Introduction to finite element analysis

the long version

"The authors believe that users of finite element analysis (FEA) software products must have a basic understanding of how mathematical models are constructed; what are the essential assumptions incorporated in a mathematical model; what is the algorithmic structure of the finite element solution; how the accuracy of the computed data can be assessed, and how to avoid common pitfalls and mistakes. The primary objective in assembling the material presented in the book is to provide a basic working knowledge of the finite element method. A professional quality software product will also be made available to the reader providing over 400 parameter-controlled examples of solved problems."-- "The primary objective in assembling the material presented in the book is to provide a basic working knowledge of the finite element method"--
