It is of considerable engineering significance to obtain parameters of uniaxial material constitutive relationships by using an indentation method for in-service engineering components,small dimensional components and welding structure materials,and it is useful to estimate the indentation hardness parameters of a material by its constitutive relationship. Based on the theory of indentation tests and elastic-plastic finite element analysis (EPFEA) with contact elements, a linear relationship between the energy ratios and yield stresses is obtained, and a cone indenter test method named constitutive relationship based on the energy method of indentation (CR-EMI) is presented to predict such key parameters of constitutive relationships of metallic materials as elastic modulus, yield stress and hardening index. Furthermore, a method is given named hardness based on energy method of indentation (H-EMI) based on the Hollomon constitutive model to forecast the hardness. The validity and accuracy of the CR-EMI method and the H-EMI method are proved by the indentation tests and finite element analyses of several metals.
