A number of independently found empirical laws for the occurrence of Hertzian ring cracks are all equivalent and can be put in the form of an energy scaling law. It is suggested that this is the true explanation of the observed size effects, which would then lie in the dynamical similarity relations of geometrically similar stress fields and fracture surfaces.
