A thoroughly revised and updated edition of the classic text on surface mechanics, this book provides a rigorous derivation of surface properties such as temperature and deformation using continuum mechanics. The discussion is animated by the authors' decades of experience in experimental mechanics. This new edition has been updated to include many techniologically motivated problems and solutions, especially computer solutions. Intended for graduate students of mechanics and mechanical engineering, the book will also be of interest to applied mathematicians and others interested in tribology.
