摘要

Critical impact velocity (CIV) of oxygen-free high-conductivity (OFHC) copper is experimentally measured with a novel facility in a gas gun system.The results are compared with the theoretical predictions using the typical constitutive relations,and the measured CIV value is much lower than the predictions.
