Tribology of ElastomersIn spite of the practical importance of the friction, wear and lubrication of elastomers, limited literature is available on this topic. Addressing these needs, this book will give readers a complete understanding of rubber tribology and the key developments in this field over the last ten years. For the first time new and important achievements such as theories of rubber abrasion and surfacial mechanochemical effects of rubber wear are presented. The book pays special attention to the principles of rubber wear – a clear understanding of which is essential for those striving towards further increasing the working life of rubber. * Comprehensively and systematically covers main points of rubber tribology * The original choice of contents informs readers of the latest developments in the field*Meeting the needs of various readers - researchers, engineers, technicians, graduates |

Page 7 - ... friction force — the resisting force tangential to the interface between two bodies when, under the action of an external force, one body moves or tends to move relative to the other. Hertzian contact area — the apparent area of contact between two nonconforming solid bodies pressed against each other, as calculated from Hertz' equations of elastic deformation.

MAIN CONCEPTS AND DEFINITIONS External friction of solids is a complex phenomenon depending on various processes that occur in the real areas of contact and in thin surface layers during relative tangential movement of the bodies. By the frictional force T is meant the force of resistance to relative displacement of solids, which is directed oppositely to this displacement. The external forces...
