Characterizing biphasic material properties with Hertzian indentation

This resources comes from a publication in Tribology Internation: Experimental characterization of biphasic materials using rate-controlled Hertzian indentation. The manual below provides instructions for the MS Excel solver template we have created to fit individual indents to the Hertz model and the rate-dependent modulus response of biphasic materials to their biphasic material properties (permeability, aggregate modulus, tensile modulus).
