Abstract
In this paper a high strain rate is defined as high if the dislocations that produce the plastic strain must move at velocities of the order of, or larger than the shear wave velocity a2. Except possibly in the initial portions of stress strain curves dislocation velocities are much smaller than a2. Only in shock loaded specimens should very fast dislocation velocities exist. An approximate analysis is made to show how supersonic dislocations in a shock wave interface (the Smith interface) can produce a hydrostatic stress behind the interface.
