Tribology is the science of friction, lubrication and wear of moving components. Results obtained from tribology are used to reduce energy losses in friction pro cesses, to reduce material losses due to wear, and to increase the service life of components. Contact Mechanics plays an important role in Tribology. Contact Mechanics studies the stress and strain states of bodies in contact; it is contact that leads to friction interaction and wear. This book investigates a variety of contact problems: discrete contact of rough surfaces, the effect of imperfect elasticity and mechanical inhomogeneity of contacting bodies, models of friction and wear, changes in contact characteristics during the wear process, etc. The results presented in this book were obtained during my work at the Insti tute for Problems in Mechanics of the Russian Academy of Sciences. The first steps of this research were carried out under the supervision of Professor L. A. Galin who taught me and showed me the beauty of scientific research and solutions. Some of the problems included in the book were investigated together with my col leagues Dr. M. N. Dobychin, Dr. O. G. Chekina, Dr. I. A. Soldatenkov, and Dr. E. V. Tor skaya from the Laboratory of Friction and Wear (IPM RAS) and Prof. F. Sadeghi from Purdue University (West Lafayette, USA). I would like to express my thanks to them. I am very grateful to Professor G. M. L.

Klappentext

Tribology is a science of friction, wear and lubrication of moving components. Advances in tribology have made it possible to considerably reduce energy and material losses in machines and during technological processes. Mechanics of solids, in particular contact mechanics and fracture mechanics, is a powerful tool for investigation of basic tribological problems. br/ This volume suggests new formulations and methods of solution of contact problems, describing specific features of friction interaction essential for tribology. These problems take into account the discreteness of contact of rough surfaces, surface inhomogeneity, properties of an intermediate medium, complicated boundary conditions, surface fracture, shape variations of surfaces in wear processes, and so on. The solutions of these problems are used to describe the friction and wear processes, to predict their characteristics for given loading and friction conditions, and to determine the optimal parameters of surface treatment for increasing the service life and reliability of moving components. Most solutions presented in the book are expressed in the closed form. br/ This book will be helpful to engineers and researchers in the field of contact mechanics and tribology. It can be recommended as a supplementary text for graduate and post-graduate students.
