On Detonation Diffraction in Condensed-Phase Explosives

A recently proposed higher order theory including shock acceleration effects for detonation shock dynamics (DSD) is evaluated for PBX-9502. Comparisons of detonation diffraction in PBX-9502 are made between experiment, multi-material simulations using the calibrated equation of state and reaction rate, and DSD simulations using the computed higher order relation for PBX-9502. The equation of state and reaction rate developed predicts the corner-turning distance for PBX-9502. The higher order DSD relation predicts a small dead zone at the corner, an improvement over the quasi-steady theory.
