The Effect of Reflected Blast Waves in HDPE Mortars

K. L. Kosanke and L. T. Weinman

A recent article discussed a problem with some comet shells exploding as they were being fired, and thus seriously damaging the HDPE mortars being used.[1] Included in the article were photographs of the two mortars that had been damaged. In these photos, it was clear that, while both ends of the mortars received serious damage, the middle section of the mortars received less damage in one case and no damage in the other. This raised a question in the minds of some readers, how could a single explosion damage both ends of a mortar while leaving the middle of the mortar essentially undamaged? The purpose of this article is to address that question.
