The application of an extended Rusinek-Klepaczko constitutive equation to predict the mechanical response of 6082-T6 aluminum under the Taylor impact test conditions was presented in this article. The numerical results obtained in the study were verified through a comparison with the experimental data extracted from the Taylor anvil-on-rod impact experiments. It was concluded that the extended Rusinek-Klepaczko constitutive model predicts the behavior of the tested aluminum alloy under applied loading conditions with satisfactory accuracy. Moreover, it was found that the plastic wave phenomenon in this material is very limited and that there was no region of constant plastic wave velocity. Strain rates up to 1.6 x 10(4) s(-1) were recorded during the Taylor impact experiments; therefore, this value may be set as the upper limit of the extended Rusinek-Klepaczko model for the alloy, which was validated with the anvil-on-rod experiment.
