Abstract

A new method for determining the elastic modulus from Hertzian contact experiments has been developed. The test surfaces are polished and coated with a thin layer of gold/palladium and then indented with a small sphere. The contact removes the coating from the contact area and the size of this can, therefore, be readily measured in an optical microscope. A simple analysis based on Hertz equations is then used to derive the modulus. The elastic modulus of glass and several ceramics is reported.
