Abstract

Over the past two decades, significant advancements have been made in energetic materials, particularly in developing insensitive munition explosives (IMXs) by research institutions such as the Swedish Defence Research Agency and the Picatinny Arsenal in the US. These advanced IMXs have progressively replaced conventional explosives like Comp B and TNT in various military applications, including mortar and artillery shells, as well as grenades. The most commonly used IMX formulation in this research consists of 50% NTO, 35% DNAN, and 15% RDX which is loaded into shaped charge of 70 mm diameter. Theoretical studies have been conducted to assess the influence of loading density on the explosive performance and shaped charge characteristics and its penetration capability. The density of the explosive has been varied from 1.6 to 1.81 g/cm³, the latter being the theoretical maximum density (TMD). Results indicate that increasing the density enhances the detonation velocity from 7015 m/s to 8050 m/s, as determined using the Explo5 code. Additionally, JWL parameters derived from Explo5 were applied in Autodyn simulations, demonstrating that jet velocity increased from 6030 to 7150 m/s. Correspondingly, penetration depth into rolled homogeneous steel (RHA) improved from 14.5 to 18.9 cm.
