Abstract
The purpose of this research is to systematically study the influence of peak-shock pressure and second-phase reinforcement on the structure/property response of shock-loaded 6061-T6 Al-alumina composites. The reload stress-strain response of monolithic 6061-T6 Al showed no increased shock hardening compared to the unshocked material deformed to an equivalent strain. The reload stress-strain response of the shock-loaded 6061-T6 Al-alumina composites exhibits a lower reload yield strength than the flow stress of the starting composites. Wavespeed measurements of shock-prestrained specimens showed no degradation compared to un-shocked specimens, and reload stress-strain response of the shock-prestrained composites, after resolutionizing and T6 aging, showed that the composites recovered their full as-received stress-strain responses.
