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.

Continuum Mechanics is a branch of physical mechanics that describes the macroscopic mechanical behavior of solid or fluid materials considered to be continuously distributed. It is fundamental to the fields of civil, mechanical, chemical and bioengineering. This time-tested text has been used for over 35 years to introduce junior and senior-level undergraduate engineering students, as well as graduate students, to the basic principles of continuum mechanics and their applications to real engineering problems. The text begins with a detailed presentation of the coordinate invariant quantity, the tensor, introduced as a linear transformation. This is then followed by the formulation of the kinematics of deformation, large as well as very small, the description of stresses and the basic laws of continuum mechanics. As applications of these laws, the behaviors of certain material idealizations (models) including the elastic, viscous and viscoelastic materials, are presented.

This new edition offers expanded coverage of the subject matter both in terms of details and contents, providing greater flexibility for either a one or two-semester course in either continuum mechanics or elasticity. Although this current edition has expanded the coverage of the subject matter, it nevertheless uses the same approach as that in the earlier editions - that one can cover advanced topics in an elementary way that go from simple to complex, using a wealth of illustrative examples and problems. It is, and will remain, one of the most accessible textbooks on this challenging engineering subject.

Significantly expanded coverage of elasticity in Chapter 5, including solutions of some 3-D problems based on the fundamental potential functions approach New section at the end of Chapter 4 devoted to the integral formulation of the field equations Seven new appendices appear at the end of the relevant chapters to help make each chapter more self-contained Expanded and improved problem sets providing both intellectual challenges and engineering applications
