ABSTRACT
A lubricated contact is a very complex system. A number of different mechanical, heat generation and transfer, chemical, and failure phenomena are taking place in a lubricated contact. We will focus only on mechanical and heat generation and transfer phenomena. These phenomena include mechanisms of elastic surface displacements and lubricant flows. Further, it is assumed that lubricated contacts always operate within the range of elastic deformations, i.e., conditions of plastic deformations are never realized. The purpose of this chapter is to establish the necessary relationships for surface elastic displacements, equations of fluid motion, and heat generation and transfer. In addition to that, we will establish some classic solutions of contact problems of elasticity for dry contacts which will benefit the development of the theory of elastohydrodynamic lubrication.
