Abstract

Shock-induced elastic-plastic deformation in pure aluminum was examined at 4 GPa peak stress by measuring wave profiles in thin (40–180 μm) samples under plate impact loading. Unlike past work, large elastic wave amplitudes (∼1 GPa) and rapid elastic wave attenuation with propagation distance were observed. The combination of large elastic wave attenuation in thin samples and differences in sample thicknesses between the present and past work suggest a consistent picture of shock propagation in pure aluminum where time-dependent elastic-plastic response is confined to material very near the impact surface. The present results cannot be fully reconciled with recent shockless compression results.
