The paper presents the results of experimental investigations into the size and shape of the contact region formed by a rigid ball resting on or moving over a plane specimen of elastic or viscoelastic material. The deformation of the plane specimen base in the vicinity of the contact region is studied by a two-beam interference method. The change in shape during motion of the originally circular contact region is attributed to the asymmetry of surface deformation in front of and behind the moving body. In the case of a viscoelastic medium this is caused mainly by elastic hysteresis, whereas for an elastic medium it is caused by the forward displacement of base material in the contact region due to frictional force.
