Molecular dynamics is used to evaluate the energies of grain boundaries and their dependence on misorientation. The role of grain boundaries in the generation and propagation of defects (dislocations and twins) is evaluated in both shock compression and release. This enables a quantitative understanding of the effect of polycrystallinity on shock compression and spalling.
