TL;DRAbstract

impact face, producing a "following wave" which overtakes the shock front, corroborating observations made with the explosive wedge technique. Combined data from three shots on nominal I.7-g/cm3 PETN were treated with a direct analysis of the flow equations and simulated with a onedimensional numerical hydrodynamic calculation. Both treatments gave wave structures and decomposition fields resembling those occurring in the shock initiation of homogeneous explosives, with complete reaction occurring near the impact face before the onset of detonation at the shock front.
