Abstract
Recently, asperity theories in contact mechanics of rough surfaces have been extended in the range near full contact by elaborating on the idea of searching a corrective solution to the tensile regions of the full contact solution. The full contact solution defines a “surface” on which asperity theory can be applied. It is here shown that a very simple prediction can be made for the non-contact area, improving the accuracy near full contact with respect to the other simple solution available, that of Persson.
