Adhesion of spheres: the JKR-DMT transition using a Dugdale model

D Maugis - Journal of colloid and interface science, 1992 - Elsevier



Abstract In the Johnson-Kendall-Roberts (JKR) approximation, adhesion forces outside the area of contact are neglected and elastic stresses at the edge of the contact are infinite, as in linear elastic fracture mechanics. On the other hand, in the Derjaguin-Muller-Toporov (DMT) …
