A modified laser shot peening technique was used to generate plastic deformation in a Si crystal. The induced dislocation activity in Si crystal was studied by integrated shock dynamics and multi-scale dislocation dynamics plasticity simulations. This laser shot peening process could also be applied to other brittle materials to generate plastic deformation.
