Abstract

sides obtaining the hardness of materials, indentation test has also been developed as a popular method for investigating mechanical properites. There exist some empirical or semi-analytical methods for determining the hardness, Young's modulus and work hardening exponent from indentation experiments. In this paper, a reverse computation method is introduced to determine the elastic modulus and stress-strain curve of 01 tool steel from the Rockwell C hardness (HRC) indentation tests combining with the finite element analysis (FEA) simulation. The force-depth data from the HRC spheroconical indentation measurement is used to start an iterative FEA simulation procedure to extract the elastic-plastic stress-strain relationship which is consistent with the experimentally measured data. The reverse computation resulsts agree well with HRC test results
