Abstract:

Experiments on the HMX-based, condensed explosive PBX-9501 were carried out to validate a reduced asymptotically derived description of detonation shock dynamics DSD. The experiments, coined passover experiments have embedded disks of lead in right circular cylinders of PBX-9501. A range of dynamically changing states, with both divergent and convergent shock shapes are realized as a detonation front is created on one end of the cylinder and passes over the embedded disk of lead. The time-of-arrival of the detonation shock at the output end of the cylinder is recorded and compared against simulations using the DSD model. The experiment and DSD theory are found to be in excellent agreement and offer a high-fidelity, yet computationally efficient means for complex wave-front tracking in explosive systems.
