Indentation method was developed to evaluate mechanical properties of cold-worked material. This method uses dimensional analysis to identify the material constants of plastic constitutive equation. We applied the developed method to cold drawn austenitic stainless steel (SUS316L) rod. The estimated proof stress and pre-strain as well as stress-strain curve agreed with those obtained by micro tensile tests. It is also found that near the surface of worked rod, both proof stress and pre-strain were higher. The developed technique can quantitatively evaluate the local mechanical properties.
