Abstract

Abstract

To in-depth understand the dynamic fracture behaviors of metal materials under complex loading, based on the finite element simulation, two types of Mach stem loading experiments were designed and carried out to investigate the dynamic fragmentation of oxygen-free high-conducting copper (OFHC Cu) under complex loading. In the experiments, a powder gun was used to impact the Mach lens, and a laser particle-velocity interferometer was applied to measure the free surface velocity. And dynamic loadings with the peak pressures of 95.75 and 32.38 GPa, respectively, were achieved. Stable Mach stem loading was successfully generated, and the Mach stem-related features were consistent with the simulated ones. At the same time, two different near-surface fracture behaviors in the OFHC Cu were observed, namely the micro-spallation under high pressure and the triangular-wave spallation under low pressure, with the cracked area distributed in a convex shape. These findings have a certain value for further understanding the dynamic fracture behaviors of metal materials and can provide new experimental methods for understanding material failure under various complex loading conditions.
