This book is dedicated to our wives Helen and Mary Lou and our families for their support and patience during the preparation of this book,and also to all of our students and colleagues who over the years have contributed to our knowledge of the finite element method。 In particular we would like to mention Professor Eugenio Onate and his group at CIMNE for their help, encouragement and support during the preparation process。
