We are exploring shock compression of metals as a means to drive dislocations at high velocities. The shock front accelerates dislocations and, in the process, the deviatoric stresses are attenuated. Experimental results are compared with analyses and molecular dynamics simulations.Reference: M. A. Meyers, H. Jarmakani, E. M. Bringa, B. A.
