Author et al. presented a simple and quick method for measuring elastic modulus by utilizing Hertzian contact theory. In order to measure the elastic modulus accurately the effect of surface roughness on relative normal approach between the contacting bodies must be comprehended, so is examined by numerical analysis. The result shows that the influence of surface roughness on Hertzian contact deformation decreases with decreasing equivalent elastic modulus and with increasing normal load and with increasing the hardness of the contacting bodies. Based on the analysis a simple equation which gives the extent of surface finish necessary to conduct the measurement of elastic modulus accurately, is presented.
