Abstract
The relationship between the coefficient of friction of elastomers and the temperature and sliding velocity has been calculated for various specific pressures on the assumption that the frictional force is low and that heating up of the surface of the bodies rubbing against each other can be neglected. Qualitative agreement with experimental results was obtained. The changes in the coefficient of friction observed are explained in terms of the temperature dependence of the volumetric properties of the elastomer, Young's modulus, and the shearing strength. A formula is proposed for calculating the rate of deformation of the material in the contact zone, which depends on the radius of curvature of the hump and the sliding velocity.
