IJ~ITi!!Is 1()1111! I!I)II(~I~:s vol. I I pressure in the pre::sing to be independent of the magnitude of the entering shock, and shock hydrodynamic c;;Icttlations on the basis of the iaster (elastic wave) velocity will yield a higher pressure and lower compression than would be derived from the velocity of the collapse wave. This would lead to an erroneous description of conditions required for initiation. If. on the other hand. the sound velocity is less than that of initiating shocks, the latter have a simple step shape and there is no problem in describing their magnitudes. Perhaps the easiest way to determine if a structural wave should be expected in a particular case is to measure the sound velocity of the pressings.
