ABSTRACT
The main goal of this chapter is to provide the reader with analytic expressions and diagrams for temperature fields due to a moving heat source in contact with the surface of a body. Technological applications of such problem solutions are manifold:
• Frictional contact realized by a pin moving across the surface of a body or by rolling/sliding of a wheel on a rail is a typical case. The temperature field depends on the boundary conditions (see, e.g., Ref. 1 for an insulated surface and Refs. 2 and 3 for a convective surface). The temperature field connected to fretting is reported in Ref. 4. The temperature field in a work roll during strip rolling falls into this category of problems (see, e.g., Refs. 5 and 6). Yet another application is hot spotting in the contact of two ideally parallel planes such as brakes and clutches. The input of heat into the rotating part may be inhomogeneous and frequently will concentrate to local spots because of asperities and/or thermoelastic instability phenomena (see, e.g., Refs. 7 and 8).
