The back cover picture shows four panels, each a still from a movie made using the NOBEL AMR (Automatic Mesh Refinement) Eulerian reactive hydrodynamic code. Panel 1: Density plot of the impact of a 5 mm radius steel projectile on a PBX9404 sample at 0.65 km/s, showing no detonation. Panel 2: Unburned explosive plot of the impact of a 5 mm radius steel projectile on a PBX9404 sample at 0.65 km/s, showing no detonation. Panel 3: Density plot of the impact of a 5 mm radius steel projectile on a PBX9404 sample at 0.70 km/s, showing detonation. Panel 4: Unburned explosive plot of the impact of a 5 mm radius steel projectile on a PBX9404 sample at 0.7 km/s, showing detonation. Figures 1 and 2 of Lee's paper in this edition of Propellants, Explosives and Pyrotechnics were developed from such pictures. Details are discussed in the article by Peter R. Lee on page 1214 ff.
