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.
