Abstract
Abstract Assume a rigid sphere that is slightly pushed towards an elastic half space. The applied force on the half space can be easily calculated using the basic theoretical tools provided by the Hertzian contact mechanics theory. It should be noted that the aforementioned analysis is valid under the condition that the deformation depth is significantly smaller compared to the sphere’s radius ( h ≪ R ). So, a significant question arises; what if the sphere is pushed deeper in the elastic half space (e.g. h > R )? In this paper, the aforementioned question is answered and a relative discussion regarding the application of the results is presented.
