A new setup was designed for dynamic tension of metal ring. The line initiation by exploding wire was used in the designed setup. The dynamic tensile experiments of OFHC copper rings at high strain rate were carried out by the designed setup. The radial velocity histories of OFHC copper rings were measured by a laser displacement interferometer. The stress-strain-rate relations for OFHC copper were obtained by processing the radial velocity histories of OFHC copper rings.
