Phenomena of contact between deformable bodies or between deformable and rigid bodies abound in industry and in everyday life. A few simple examples are brake pads with wheels, tires on roads, and pistons with skirts. Common industrial processes such as metal forming and metal extrusion involve contact evolutions. Because of the importance of contact processes in structural and mechanical systems, considerable effort has been put into modeling and numerical simulations.

This book introduces readers to a mathematical theory of contact problems involving deformable bodies. It covers mechanical modeling, mathematical formulations, variational analysis, and the numerical solution of the associated formulations. The authors give a complete treatment of some contact problems by presenting arguments and results in modeling, analysis, and numerical simulations.

Variational analysis of the models includes existence and uniqueness results of weak solutions, as well as results of continuous dependence of the solution on the data and parameters. Also discussed are links between different mechanical models.

In carrying out the variational analysis, the authors systematically use results on elliptic and evolutionary variational inequalities, convex analysis, nonlinear equations with monotone operators, and fixed points of operators.

Prerequisites include basic functional analysis, variational formulations of partial differential equation problems, and numerical approximations. The text is suitable for graduate students and researchers in applied mathematics, computational mathematics, and computational mechanics.

Titles in this series are co-published with International Press, Cambridge, MA.


Graduate students and research mathematicians interested in applied mathematics, computational mathematics, and computational mechanics.


"A need for a clear unified representation of the many results has been recognized ... This need is, in part, fulfilled by this monograph, which presents in a unified way a comprehensive collection of very recent results on models dealing with quasistatic contact between viscoelastic or viscoplastic bodies. This makes the results easy to access and study."

-- Mathematical Reviews

"The book deserves recommendation to all who are interested in the theory and applications of evolutionary variational inequalities."
