Abstract

In order to evaluate the influence of bulk metallic glass size on its impact toughness, a typical Zr-based bulk metallic glass is selected for numerical simulation research in this paper. The study uses the JH-2 constitutive model to describe its mechanical response under impact loading, and the impact toughness values are obtained for different cross-sectional areas, heights and spans using the FEM-SPH method. The results show that an increase in cross-sectional area and span leads to an increase in impact toughness, while an increase in height leads to an increase and then a decrease in impact toughness, with the highest value for the impact toughness at the square cross-section. These results provide ideas for improving the impact toughness of large metallic glasses.
