As the interest in adhesion is shifting towards smaller and smaller scales, the well known Tabor adhesion parameter decreases and the DMT theory is frequently considered to be the appropriate limit. A very attractive much simplified version of DMT has been proposed in a recent investigation of rough contacts by Pastewka & Robbins (PNAS, 111(9), 3298-3303, 2014) which seems to work in very general conditions in numerical experiments. However, when comparing this calculation to the known theories for the sphere, surprisingly large conflicts occur, and the reason for the success of the numerical experiments is obscure.
