Modeling two-dimensional shock initiation and detonation-wave phenomena in PBX 9404 and LX-17

The ignition and growth concept of reactive flow in heterogeneous solid explosives is incorporated into a two-dimensional, finite element, Lagrangian code and used to model shock initiation and detonation wave propagation experiments on PBX 9404 and LX-17. The failure radii and corner turning abilities of detonating PBX 9404 and LX-17 are calculated. Two-dimensional shock initiation experiments on LX-17 which produce both failing and diverging detonation waves are accurately simulated.
