【 摘 要 】

The attenuation properties of an impact initiated PBX-9501 explosive through several thicknesses of CeO₂ powder is investigated. The CeO₂ is at an initial porous density of 4.0 g/cm³ , roughly 55 % of theoretical maximum density. Measurements of the input (into the powder) and propagated (through the powder) wave profiles are measured using optical velocimetry. Results show a reduction of the average wave speed, C_X, and peak steady-state material velocity, uP , with increasing powder thickness from 1.5 - 5.0 mm.
