From the reviews:
"This is a textbook devoted to finite element methods (FEMs). ... As a whole, this book is an introductory tutorial from mathematical standpoint, convenient for students with moderate mathematical knowledge and training." (Fumio Kikuchi, Zentralblatt MATH, Vol. 1160, 2009)
"This book addresses a very popular topic, finite element methods (FEM)--a powerful engineering tool. The availability of commercial FEM software allows engineers and researchers to get approximate results for many engineering problems that are hardly solved by a pure theoretical approach. ... This book will be a very useful theoretical reference for people who are trying to develop a new type of finite element. ... Summing Up: Recommended. ... upper-division undergraduates through professionals with a strong mathematical background." (X. Le, Choice, Vol. 46 (11), 2009)
