Adhesive Contact between a Rigid Cylinder and an Elastic Layer

In micro/nano tribology, micor/nano contact is the basis of mcro/nano friction, lubrution and wear. In micro/nano contact, the adhesive contact between a rigid body and an elastic layer is an important issue. This issue is applied in coating, polymer film contact and bio-tribology. In the past, there are few researches on the adhesive contact between a rigid cylinder and an elastic layer. Most researches related to this topic used analytical method and only complex integrals are obtained. Thus, it is difficult to obtain the results. This research use boundary element method to investigate the adhesive contact between a rigid cylinder and an elastic layer. There are four parameters that affect the adhesive contact: Tabor parameter, cylinder radius, Poisson’s ratio and layer thickness. This research investigates the effects of Poisson ratio and layer thickness on the adhesive contact between a rigid cylinder and an elastic layer. Lennard-Jones potential and Derjagiun approximation are used to simulate the traction. This research will investigate the load-approach relation, contact radius-load relation, traction distribution, deformation distribution and pull-off force vs. Tabor parameter. The research for the adhesive contact between a rigid cylinder and an elastic layer will become complete by the proposed research. Thus, the research for micro/nano contact will make great progress.
