Abstract
In many applied problems, the main role is played by the total length L of real contacts between two rough surfaces rather than by the contact area. The dependence of the total contact length on the pressing force F for arbitrary fractal surfaces has been studied for the first time and it is established that this dependence is described by scaling relation L ∝ F 3/4.
