Effect of Explosive Charge Geometry on Boundary Surface Peak Pressure with Regard to Standoff Distance

In an effort to better understand the effect of explosive charge geometry on blast effects, in particular with regard to standoff distance, this paper presents a study of three different geometries at varying standoffs. The geometries reviewed in this study were: cylinder, sphere, and rectangular cuboid. The explosive mass was held constant between all geometries, and the system was modeled with the LS-DYNA® structured Arbitrary Lagrangian-Euler (ALE) solver. The peak pressure on a reflective boundary surface was measured and recorded in order to quantitatively categorize the blast effects of each case.
