Abstract：In order to study the dynamic mechanical property of 2A16 aluminum alloy and the influence of heat treatment on its strain rate sensitive property, tests for 2A16 aluminum alloy(heat-treated condition O and T4) under quasi-static and intermediate strain rate were performed by using an electronic universal testing machine and a high velocity hydraulic servo-testing machine at room temperature. The stress-strain curves under different strain rates were obtained, and a modified Johnson-Cook constitutive model was fitted. The results show that the heat-treated condition has a big influence on the strain rate sensitive property of 2A16 aluminum alloy between 10-4~102s-1, and the strain rate hardening effect of 2A16-O aluminum alloy is obvious but which for 2A16-T4 aluminum alloy is not obvious, in addition, the strain hardening effect is obvious for both of the materials between 10-4~102s-1. Moreover, the modified Johnson-Cook constitutive model can predict the test results very well.
