Use of combined elastic modulus in depth-sensing indentation with a conical indenter

Abstract

Conventional methods of analysis for depth-sensing indentation test data use the slope of the elastic unloading portion of the load-displacement response in conjunction with the elastic equations of contact for a rigid cone. It is common practice to incorporate the combined modulus of the indenter and specimen in these equations although the validity of this practice never appears to have been verified. This work demonstrates the validity of using the combined elastic modulus in depth-sensing indentation testing in conjunction with the elastic equations of contact for a conical indenter.
