Abstract
Simulation of the shock compression of polycrystalline α-iron at the mesoscale has been carried out using a two-dimensional, quasi-MD code. Grains of about 15 μm are randomly distributed to simulate the polycrystal. Results show the presence of a particle velocity dispersion comparable to the level observed experimentally. Other unique features include an eddy-like velocity field (meso rotation) and chaotic wave fronts.
