Abstract

We present the results of a study aimed at characterizing the impulse produced by the detonation of milligram charges of lead styphnate explosive at pressures ranging from 1 to 1000 mBar. A combined analytical/numerical approach based on either the vacuum expansion or the classical strong blast models is used to compute the impulse imparted by the explosion on a solid hemispherical surface. It is found that the vacuum expansion model agrees reasonably well with experiments performed at the lowest pressures, and that the predicted trends are indeed observed in practice. Poor agreement is observed with a strong blast model and this underscores the fact that its applicability depends on both the length scale of problem and the ambient pressure.
