abstract = {We present the numerical results for the viscoelastic and
adhesive contribution to rubber friction for a tread rubber
sliding on a hard solid with a randomly rough surface. In
particular, the effect of the high- and low-frequency
roughness power spectrum cut-off is investigated. The
numerical results are then compared to the predictions of an
analytical theory of rubber friction. We show that the
friction coefficient for large load is given exactly by the
theory while some difference between theory and simulations
occur for small loads, due to a finite sample-size effects,
whereas the contact area is almost unaffected by the low
frequency cut-off. Finally, the role of a finite rubber
thickness on viscoelastic friction and contact area is
introduced and critically discussed. Interestingly, we show
that classical rough contact mechanics scaling rules do not
apply for this case.},
