Using large-scale molecular-dynamics simulations, we have studied the propagation of elastic and plastic waves in three-dimensional crystals oriented along low-index directions. We have observed elastic precursors, followed by steady plastic waves (depending on propagation direction), which are the result of both simple, and quite complex, modes of plastic deformation. We present a review of earlier results, methods of computation and visualization, and prospects for further areas of study.
