Abstract
The numerical simulation based on the Lennard-Jones potential for the adhesive contact between spheres is employed. The result is compared with the Maugis-Dugdale model. An empirical formula is obtained for fitting the relation between the Tabor parameter and the pull-off force for the numerical simulation. By using the empirical formula, the equations for approach versus load and the Tabor parameter versus the contact radius at zero load can be found. All these equations are both simple and as accurate as the numerical simulation.
