We proposed an improved technique to determine the plastic properties of material from the load-displacement curve from ball indentation test. The reverse finite element method was used for simulation of indentation test. This technique has been successfully applied on several carbon steel specimens and for all these test materials the reverse analysis results were found to agree with the data from conventional standard test method. This nondestructive assessment of deformation behavior has good potential for the other materials.
