Abstract A novel high-speed tensile facility (HSTF) with special fixture is applied to research the dynamic failure characteristics of oxygen-free high-conductivity (OFHC) copper bars at different levels of strain. The experimental tests are numerically simulated involving void evolution. It is indicated that the localized strains at necking region computed with the adjusted Johnson–Cook model and the Zerilli–Armstrong model are consistent with the experimental results.
