Abstract: We have performed a series of plate impact experiments to study the strength and spall damage behavior of S200F Be. Peak stresses achieved were in the range from 5.6–19.2 GPa. VISAR data show long rise times in the approach to the shocked state believed to be the result of twinning occurring alongside or in deference to slip in this hep material, with its free surface never achieving a steady velocity. These data indicate brittle spall behavior with spall strengths in the range of 0.8–0.9 GPa. In experiments where target thickness is varied, we see evidence of precursor decay and present calculations of the Hugoniot Elastic Limit (HEL).
