Computer simulations were presented which showed that edge dislocations could be generated by purely kinematic processes, in the absence of more usual dislocation sources. New dislocation pairs could be generated near to high-velocity dislocations. These kinematic processes were active only under high stresses, but were expected to be important under shock-loading or other high strain-rate conditions. Such dislocation generation was possible because the sign of the force between edge dislocations changed when the dislocation velocity exceeded the Rayleigh velocity.
