AN ANALYSIS OF THE FINITE ELEMENT METHOD
"If you're a numerical analyst or an engineer interested in the basic
theory of the finite element method, this book belongs on your
shelf. If you have no interest in finite elements but enjoy
well-written mathematical literature, this book still belongs on your
shelf. Though some sections are dated, the contents of this book
remain a solid foundation for understanding the behavior of finite
element techniques in theory and in practice. Furthermore, while the
contents are mathematically rigorous, the authors largely avoid the
theorem/lemma/proof of most mathematical books, and instead describe
the analysis in an almost conversational tone. Reading Strang and Fix
reminds me of reading Lanczos: the book is dense with ideas which are
both mathematically and practically interesting, but the presentation
is so smooth that one can almost read it as one reads a novel."
