Dynamic mechanical performance and constitutive model for Zr58Cu12Ni12Al15Nb3 metallic glass
In this study, compression tests under quasi-static and dynamic states and plate impact experiments were performed on Zr58Cu12Ni12Al15Nb3 bulk metallic glass (BMG). The experimental results demonstrated that the BMG specimen fractured catastrophically without noticeable plastic deformation. Therefor...

| description | In this study, compression tests under quasi-static and dynamic states and plate impact experiments were performed on Zr58Cu12Ni12Al15Nb3 bulk metallic glass (BMG). The experimental results demonstrated that the BMG specimen fractured catastrophically without noticeable plastic deformation. Therefore, the Johnson-Holmquist II (JH-2) constitutive model was used to describe the mechanical response of the presented alloy. The constitutive parameters of the Zr-based BMG were determined from the experimental results based on the JH-2 constitutive equations. Subsequently, the constitutive model with the presented material parameters was programmed in the commercial finite element analysis software LS-DYNA to simulate the dynamic compression and penetration process. The good agreement between the numerical simulations and experimental results indicates that the obtained JH-2 constitutive parameters are accurate and effective. |
