Abstract:
The aluminum alloy 5083 in tempers such as H32 and H131 is an established light-
weight armour material. While its dynamic response under high strain-rates has
been investigated elsewhere, little account of the effect of material
orientation has been made. In addition, little information on its strength under
such loadings is available in the literature. Here, both the longitudinal and
lateral components of stress have been measured using embedded manganin stress
gauges during plate-impact experiments on samples with the rolling direction
aligned both orthogonal and parallel to the impact axis. The Hugoniot elastic
limit, spall, and shear strengths were investigated for incident pressures in
the range 1–8 GPa, providing an insight into the response of this alloy under
shock loading. Further, the time dependence of lateral stress behind the shock
front was investigated to give an indication of material respons
