The present research proposes a simple and accurate method for hardness calculation.The keypoint of this study is that the influence on hardness by the yield stress and hardening modulus can be considered as being detachable approximately.It makes it easy to induce an empirical correlation between the hardness and the material properties such as the yield stress and hardening modulus.This method was created from the numerical hardness results of many kinds of elastic-linear-hardening materials with their relative hardening moduli ranging from 0.83 to 25.00.Using the present method,we can calculate the Brined hardness with the yield strength and hardening modulus immediately.The calculation error is less than about 6% compared with the accurate numerical results.
