Abstract A mathematical model developed previously for predicting adhesive sliding friction of rubber on a hard surface in the presence of Schallamach waves is extended here to include global effects of viscoelasticity, besides the previously included viscoelastic effects in the neighborhood of the debond (shear crack) tips; the crack tip model is unchanged. We find that global viscoelasticity limits the maximum sliding speed and minimum wavelength for which a wave train can exist and, as expected, increases the friction force. The model is shown to improve upon the agreement with experimental data on wave speed and wavelength in the previous paper.
