This thoroughly revised and updated edition of the classic text on surface mechanics preserves the objectives of the original: the rigorous derivation of surface properties such as temperature and deformation from the differential equations of continuum mechanics. From such solutions for the surfaces of single bodies one can then formulate problems involving two bodies at rest or in relative motion in terms of a singular integral equation. The discussion is analytical and theoretical, but animated by the authors' decades of experience in applications and experimental mechanics. This new edition has been updated to include many technologically motivated problems and solutions, especially computer solutions. Beginning with a survey of the field equations of classical continuum mechanics, the book continues with a discussion of surface temperatures in moving bodies. It then turns to semi-infinite and layered elastic media, discussing stress and deformation as well as thermal stress and associate deformation fields. Treatments of viscoelasticity and perfect plasticity concentrate on semi-infinite solids; these are followed by a discussion of rough surfaces.The book concludes with a lengthy chapter of applications. An appendix discusses integral equations. Intended for graduate students of mechanics and mechanical engineering, the book will also be of interest to applied mathematicians and others interested in tribology.

At the conclusion of the Conference on Tribology in the area of Wear Life Pre­ diction of Mechanical Components, which was held at the General Motors Research Laboratories and sponsored by the Industrial Research Institute, a very high pri­ ority recommendation was modeling of tribological systems. Since the appearance of the Conference Proceedings in 1985, the writers discussed the matter of modeling with Dr. Edward A. Saibel, Chief of the Solid Mechanics Branch, Engineering Sciences Division, U.S. Army Research Office. This discussion led to a proposal for the Workshop which resulted in this volume. The choice of proposal and Workshop name turned out to be more restricted than it needed to be. As such, the Workshop adopted the name for this volume, Approaches to Modeling of Friction and Wear. By design, the attendance was restricted to not more than 40 individuals so as to allow small group discussions. There were four panels which deliberated on the same questions after two invited area lectures. Section 1 contains the substance of the two lectures. Section 2 is the Workshop Summary which is a distillation of the four panel reports by the entire Workshop attendance. This was formally written up and edited by the eight panel session chairmen, i.e., each of the four panels met twice on two different questions under the leadership of a chairman for each session. Section 3 contains four brief position papers on the subject of the Workshop.
