"Explicit Relative Contact Pressure Expression: Dependence Upon Surface Roughness Parameters and Vickers Microhardness Coefficients"

Abstract: An explicit expression for the contact hardness and the relative contact pressure is developed. This expression is simple and clearly shows the dependence of the contact hardness and the relative contact pressure upon the Vickers microhardness correlation coefficients and the surface roughness parameters. Parametric studies of the contact conductance are performed and it is shown that theoretical predictions and experimental data are in good agreement.
