Study on mechanical properties of 6061-T6 aluminum alloy

Abstract

In order to obtain the accurate mechanical properties of 6061-T6 aluminum alloy, the tensile test of 6061-T6 aluminum alloy was carried out on a high-speed material testing machine, and the tensile test data of 6061-T6 aluminum alloy at different rates were obtained. Then, the Johnson-Cook constitutive model was introduced, and the formula was simplified based on the experimental conditions. The constitutive parameters were obtained by the stepwise estimation method, and the Johnson-Cook (JC) constitutive model of 6061-T6 aluminum alloy was established. Comparing the model prediction results with the experimental data, the prediction curves are in good agreement, which verifies the feasibility of the model.
