On the shape of surface under the ball rolling on a viscoelastic base

In the presented paper the depth of conclave resulting under the hard ball rolling on the visco-elastic base is calculated by use of various simple rheological models (Maxwell, Voigt and 3-parameter model).
The width of air gap resulting between the ball and deformed surface in the rear part of contact area is measured by use of interference method and next the experimental values are compared with the theoretical ones. The latter have been obtained under the assumption that the continuous distributions of relaxation and retardation times may be replaced by the discrete ones.
