Abstract

In this paper, we studied the quasi-static performance and the dynamic compression and tensile properties of the Q235 steel at temperatures ranging from the room temperature to 900℃ using a universal testing machine and the split Hopkinson bar system. Based on the experimental results, we modified the thermal softening item in the Johnson-Cook (J-C) constitutive model and proposed a revised J-C constitutive model for Q235 steel, which we then validated using Taylor impact experiments and corresponding numerical simulations.
