Extracting the plastic properties of metal materials from microindentation tests : Experimental comparison of recently published methods

Experimental verifications have been performed on three engineering metals to verify recent methods proposed for extracting stress-strain curves from indentation tests. Their sensitivity to data errors is evaluated. Finally, the factors that might cause the inaccuracy and instability of the proposed methods are discussed, providing information that can be useful for further improving these methods. © 2007 Materials Research Society.
