This document offers a new numerical solution to analyze the transition from Hertzian point contact in elastic field to elasto-plastic and full plastic contact as function of Brinell Hardeness number, considering uniform Yield in subsurface. The method takes into account a slice techniques and surface HB value limitations. Results are compared to literature data for Hertz point contact and with standard test method for Brinell hardness.
