The Hertz theory applies only when the compressive forces acting on two spheres in contact with one another are comparatively small, and the stresses produced therefrom remain within the yield point of the material. In most of the practical cases encounted in engineering, however, the compressive forces are so large that the Hertz conditions are not satisfied, and a partial or complete distribution of constant yield pressure results on the surface of contact. This has so far been verified experimentally by some investigators. To help numerically evaluate such a pressure distribution, one approximate analysis method is proposed, by means of which the relations between load and deformation either for the case of loading or unloading (increasing or decreasing compressive forces) can be established. For generality the variables, geometrical or physical, appearing in the expressions derived are given throughout in dimensionless form.
