Abstract

Abstract

It is very important to establish the material model for the explosive forming and penetration simulation of ZrCuNiAlAg bulk amorphous alloy. In this paper, the JH-2 model parameters of the ZrCuNiAlAg bulk amorphous alloy were calculated by the experimental results. In order to verify the accuracy of the ZrCuNiAlAg bulk amorphous alloy JH-2 model, the finite element model of plate impact test was established by Autodyn. The deformation process of ZrCuNiAlAg bulk amorphous alloy under high pressure and high strain rate was simulated. Compared with the experimental results, the average velocity deviation of the free surface particles on the back surface of the target plate is less than 3%. It is shown that the JH-2 model of ZrCuNiAlAg bulk amorphous alloy can well describe the mechanical behavior of the material under large deformation, high strain rate, high pressure and other environmental conditions, and the accuracy of JH-2 model of ZrCuNiAlAg bulk amorphous alloy is verified.
