英文摘要	In this study, we focus on the dynamic failure property of A6N01S-T5 aluminum alloy use for high-speed trains. The method of split Hopkinson tensile bar (SHTB) and three-dimensional (3D) digital image correlation (DIC) was put forward to find the dynamic mechanical properties and dynamic failure strain of A6N01S-T5 aluminum alloy, and on the basis of this, Johnson-Cook model constitutive parameters and dynamic failure strain parameters were obtained through a series of static and dynamic tests. An important character of this method was that the sandwich structure from the true high-speed train was used in penetration test, followed by the numerical calculation of the same working condition using LS-DYNA. Then we compare the experimental results with simulation results mentioned above in terms of failure morphology in structure and the bullet speed throughout the entire process to verify the accuracy of the parameter. The experimental results provide a data basis for the crash simulation model of high-speed trains, in turn to optimize the structural design and whole efficiency.
