Compressibilities of magnesium alloy, Lucite, and polyethylene were measured during explosively induced shock, using a flash X-ray technique. Measurements on magnesium alloy confirm earlier results from a similar experiment using small explosive charges, but show a distinctly lower compressibility than reported by other authors using free surface measurements. To a lesser extent the Lucite data show the same discrepancy. Polyethylene turns out to be less compressible than Lucite under intense shock loads.
