Abstract

The lattice level strain measured using in situ x-ray diffraction during shock compression of rolled iron foils is used along with the pressure dependent elastic constants to estimate the dynamic strength of 1±1 GPa at 15 GPa. We examine these results in the context of the constant stress (Voigt) and constant strain (Ruess) limit of grain interaction, discussing the implications at the lattice level.
