Abstract

Boundary element method is used to analyze the effect of Poisson’s ratio on the adhesive contact between an elastic sphere and a rigid half-space. Lennard-Jones potential is used for the surface traction. It is found that Poisson’s ratio does not affect the pull-off force for small Tabor parameter. As the Poisson’s ratio parameter is larger, both the jump-in distance and the jump-off distance are smaller. The contact radius is smaller for larger Poisson’s ratio at the same load. Thus, the effect of Poisson’s ratio should be taken into consideration for large Tabor parameter.
