摘要：
The mechanical properties and dynamic constitutive relation of 5A06 aluminium alloy material were investigated. The quasi-static and dynamic uniaxial tension experiments were conducted at the temperature ranging from 25℃ to 250℃ by using a universal testing machine and a split Hopkinson tension bar. As a result, the mechanical behaviors of 5A06 aluminium alloy under different temperatures and strain rates were obtained. Based on the experimental results, the temperature softening item of the Johnson-Cook strength model was modified and the material constants were calibrated by a combination of experimental tests and numerical simulations with the finite element software AUTODYN-2D. Finally, the dynamic response histories and dynamic responding characteristics of 5A06 aluminum alloy plates subjected to underwater shock loading were investigated by using numerical simulations. The results of numerical calculation agree well with the test results. It is shown that the numerical calculation model is reasonable and reliable. © 2016, Editorial Office of Journal of Vibration and Shock. All right reserved.
