Abstract In order to accurately evaluate the stress flow behavior and plastic deformation of 7050-T7351 aluminum alloy, mechanical properties tests of the aluminum alloy at different strain rates and temperatures were preformed. The constitutive models of Johnson-Cook (JC), Hartley-Srinivasan (HS) and Swift were calibrated by using the test results. And then, the corresponding finite element (FE) models were established by using the ABAQUS FE software for simulation analysis. According to the FE calculation results, the JC constitutive model was modified, and a Modified Johnson-Cook (MJC) constitutive model was adopted in this work. The strain rate and temperature multipliers of JC were coupled with HS and Swift models, and then the Taylor rod impact tests and the corresponding simulation calculation were conducted for verifying the effectiveness of three constitutive models. The results show that the JC model overestimated the stress flow behavior of 7050-T7351 aluminum alloy, while the predicted results by MJC constitutive model are in good agreement with the test. Both HS and Swift models can well reflect the stress flow behavior of the material under quasi-static conditions. The MJC model can also well predict the plastic deformation of the Taylor rods, while the modified models which couple the strain rate and temperature multiplier of JC with HS and Swift have relatively poor prediction accuracy.

Key words： flow behavior plastic deformation SHPB constitutive model Taylor rod
