Boundary element analyses on the adhesive contact between a rigid cylinder and an elastic layer bonded on a rigid half-space

Abstract

The adhesive contact between a rigid cylinder and an elastic layer bonded on a rigid half-space is investigated. In the past, several analytical models were proposed in the frame of the JKR model. In this research, boundary element method is employed. The traction is derived on the basis of the Lennard-Jones potential and the Derjaguin approximation. The whole solutions are obtained. The effects of Tabor parameter and layer thickness are investigated. The results are compared with the analytical models. The limitations of the analytical models are obtained. The empirical formulas for pull-off forces, jump-in distance, and pull-off distance are proposed.
