Abstract
The dynamic yielding and tensile fracture (spalling) behavior of an annealed aluminum–magnesium alloy is investigated using symmetric plate impact experiments. The Hugoniot elastic limit displays upper and lower yield points, with the lower yield point remaining constant near 0.33 GPa and the upper yield point increasing from 0.38 to 0.48 GPa with increasing peak stress. The dynamic fracture (spall) strength also increases with peak stress from 0.84 to 0.92 GPa.
