| Abstract: | This paper describes the nonprecise meaning of the Strain Hardening Modulus given by some large finite element softwares.According to the uniaxial tensile test the paper for the first time gives the theoritical basis for the experimental determination of the Strain Hardening Modulus and the measuring method.Basing on the obtained data,we completed the calculations of the elastic plastic forming processes of a thin sheet radiator component by the finite element method and compared the results with the data obtained by measuring the radiator. |

| Keywords: | strain hardening modulus material mechanical property elastic plastic forming finite element method |
