Perry, F C; Noack, D D

Heterogeneous shock effects were studied in aluminum (6061-T6) and single crystal lithium niobate (Z-cut) in the range 0.7 to 4.5 GPa by means of holographic interferometry. Heterogeneous yielding in lithium niobate was observed directly for the first time. In addition, nucleation or activation of defects were observed in both aluminum and lithium niobate. The single crystal data indicate that a defect-dominated fracture process constitutes a reasonable model for shock compression. The polycrystalline data suggest that similar pattern will prevail at a sufficiently high pressure.
