Abstract :
All the existing constitutive relationships are only corresponding to a special hardness and will be inapplicable when the hardness changes. Therefore, the constitutive relationship that is based on the J-C model and that considers hardness is presented in this paper through considering the influence of hardness on yield strength and tensile strength. The constitutive relationship that considers hardness is built for AISI 4340 steel and the comparison with experimental results shows that this model can correctly express the material´s dynamic mechanical performance at different hardness.
