Distribution of Heat between Sliding Surfaces

Abstract

When sliding takes place between metals of comparable hardness, the mechanism is probably restricted to single asperity interactions of a short duration. In this paper, a solution is derived for the heat conduction in a single interaction of this type and it is shown that, unless there is initially a temperature difference between the surfaces, there can be no meaningful distinction between ‘moving’ and ‘stationary’ surfaces. The solution is integrated for an arbitrary configuration and the result is considered with reference to the work of Jaeger (1)† and Blok (2).
