Shock Waves in Quasicrystals

Shock waves in quasicrystals of the AlCuLi type and in approximant crystals of the C15 Laves phase have been studied by MD simulations. Three regimes are found: at low shock wave intensity the system reacts elastically, at high intensities it is turned amorphous. In the intermediate region we find a continuous transition with growing defective domains. The intensities where the behavior changes are different for the quasicrystal and the crystal, but the behavior itself is similar.
