Use is made of its excellent deformation capabilities to initiate a metal jet for the target penetration moving with the speed of several kilometres per second. Gray and Follansbee (1988) conducted unique experiments with OFE copper specimens subject to such extreme loading conditions. Controversial results were obtained that could not be explained by any existing visco-plastic theory. The authors of this paper made an attempt at an explanation by introducing a specific viscoplastic model with time retardation. In the present work the model was cast to the format of the standard continuum mechanics equations.
