Discrete Contact Mechanics with Applications in Tribology

Discrete Contact Mechanics with Applications in Tribology presents new solutions to contact problems for elastic and viscoelastic bodies in normal, sliding, and rolling contact, taking into account effects such as surface microgeometry, adhesion, fluid films, and viscous hysteresis in bulk material or surface layers. These solutions are applied to problems in tribology for modeling contact and friction of bodies with surface microgeometry (rough or textured). The book provides exact mathematical formulations for cases of discrete contact based on classical approaches of contact mechanics, allowing readers to study the influence of different parameters of surface microgeometry on contact characteristics and friction force.The book will help solve problems in modeling contact and friction interaction in cases of discrete character of contact interaction, mutual influence of individual contact spots in contact interaction of elastic and viscoelastic solids, calculating sliding and rolling friction forces as a result of adhesive and viscoelastic mechanisms of dissipation, and more. - Provides a raft of solutions to contact problems for elastic and viscoelastic materials in normal, sliding, and rolling contact - Provides solutions and formulations that consider surface microgeometry, adhesion, fluid films, viscous hysteresis in bulk material or surface layers, and other common material effects - Features applied methods based on classical contact mechanics approaches, allowing for analytic and half-analytic treatment of problems

Irina Goryacheva is a Professor and Head of the Tribology Laboratory of Ishlinsky Institute for Problems in Mechanics. She is the author of more than 200 papers and 6 books in the field of contact mechanics and tribology and has developed analytical methods of solution of contact problems for deformable bodies with various surface geometry taking into account the effects of mutual influence of contact spots, wear, adhesion, surface films and layers, and inhomogeneity of material properties.
