Abstract
In order to investigate the shock ignition of high energy solid explosives by shock waves, we carry out Lagrangian experiments with 2-D Lagrangian technique which uses composite manganin-constantan (CMC). The effects of the shock sensitivity of pressed solid high explosives, TNT, and the effect of the lateral rarefaction wave were studied. Based on the measured pressure histories and the radial displacements, we formulate the Ignition and Growth reactive flow models for the pressed TNT. The shock initiation process simulated by Ignition and Growth model agreed well with experimental data. This pressed TNT model can be applied to shock initiation scenarios which are highly unpredictable and have not been or cannot be tested experimentally.
