Influence of surface roughness on the scatter in hardness measurements - A numerical study
Indentation hardness is usefully applied in the field of rock comminution, where high contact stresses are commonly encountered. Hardness measurements pro- vide a means for estimating the discontinuity wall strength which is required to understand the shear strength of the discontinuity. The hardness value is also used to estimate compressive strength of rocks with known density.
