Abstract The dynamic mechanical response behavior of 7003 aluminum alloy at room temperature and different strain rates was studied using a split Hopkinson pressure bar. The results show that the flow stress of the 7003 aluminum alloy increases with the increase of applied strain rate, showing a positive strain rate sensitivity. When the loading strain rate increases to 4 100 s^-1, the adiabatic temperature rise softening caused by localization of shear deformation completely counteracts the strain hardening and strain rate hardening. As a result, the flow stress decreases gradually with the increase of loading strain in the middle stage of deformation. With the increase of loading strain, the dislocation density increases due to the proliferation of dislocations. At the same time, these dislocations continue to pile up at grain boundaries, and gradually evolve into cellular dislocation substructures, resulting in the saturation of dislocation density. By optimizing the strain hardening term, strain rate coefficient C and n of the original J-C constitutive, and introducing a correction term of adiabatic temperature rise, a mechanical constitutive model which can accurately predict the stress response behavior of 7003 aluminum alloy under different deformation conditions is constructed. The deviations between the fitting results and the experimental results are all within ±10%, and the correlation coefficient (R) and average relative error (AARE) between the predicted and experimental values are 99.17% and 1.3%, respectively.
