We argue that – contrary to widespread opinion – friction between a randomly rough self-affine fractal surface and an elastomer is not a multiscale phenomenon, but is governed mostly by the interplay of only two scales – as a rule the largest and the smallest scales of roughness of the contacting bodies. The hypothesis of two-scale character of elastomer friction is illustrated by computer simulations in the framework of the paradigm of Greenwood, Tabor and Grosch using a simplified one-dimensional model.en532 Mechanik der Fluide, Mechanik der Flüssigkeitencontact mechanicsfrictionelastomerdistinct scalemulti-scalefriction modelArticle2045-232226057466
