  The force of adhesion of a rotationally symmetric indenter and an elastic
half-space is analyzed analytically and numerically using an extension of the
method of dimensionality reduction (MDR) for superimposed normal/tangential
adhesive contacts. In particular, the dependency of the critical adhesion force
on the simultaneously applied tangential force is obtained and the relevant
dimensionless parameters of the problem are identified. The developed method is
applicable straightforwardly to adhesive contacts of any bodies of revolution.
