Abstract：

Automotive crash safety is commonly predicted by simulation analysis, and its accuracy is

closely related to materials properties under high strain rates. For four kinds of automotive

aluminum alloy sheets 6016 at home and abroad, high speed tensile tests were carried out at

different stain rates(5-500 s-1), and data were analyzed by the model Johnson-Cook. Then,

their mechanical properties (yield strength, tensile strength and elongation) and the stain

rate sensitivity of crashworthiness were studied systemically. The results show that yield

strength and tensile strength of aluminum alloy sheet 6016 have a low strain rate sensitivity,

while the elongation and crashworthiness of aluminum alloy sheet 6016 have a high strain rate

sensitivity.
