The role of roughness in contact problems has a long history, since it was Leonardo da Vinci in what is known today as Codex Forster II (folii 86r and 87r) who first identified roughness (“confregazione” in his pre-Italian language) as one of the three main factors affecting friction of a body sliding on an inclined plane as in his experiments (the other two being the weight of the body, and the slope of the inclined plane), see Fig. 1 for a representative image of a rough surface.

The basic laws of friction were (re)discovered later on by Amontons and Coulomb, and the “Amontons–Coulomb” law predicts linearity between frictional load and normal load. This was explained, particularly by Greenwood and Williamson [1], as due to the effect of roughness, which promotes linearity of real contact area with load. Today, this effect is being again re-discovered to be the basic factor affecting friction even at the nanoscale, where roughness is now to be interpreted as “molecular roughness”, where asperities are defined even by single atoms [2].
In the present contribution, a computational method for the study of the frictional response of rough surfaces is proposed.
