Abstract
The lethality of ammunition, and/or the effectiveness of armour can be assessed by the penetration (or perforation) performance of the ammunition, and by the nature of the “debris” that results on the “inside” of the armour following a threat/armour interaction. The “debris” is comprised of the residual projectile and armour fragments generated during the penetration event. These fragments are referred to as behind armour debris or BA debris. The effectiveness of the projectile or the armour may be assessed with knowledge of the characteristics (mass, velocity and trajectory) of this debris cloud. Experimental techniques have been developed to measure the BA debris using “witness packs” (thin plates in which the number and nature of the resulting holes can be measured) and flash radiography (time lapse debris fragment position images). These results may be used in larger vulnerability/lethality (V/L) models, in which the effect of a range of projectiles or other threats on the total system (e.g., land, air or sea vehicles) are used to assist in design, in terms of layout and protection. The following report outlines the modeling data and techniques employed in the DeCaM version 3.0.3 software. This report has been prepared as a supplement to the project report to provide a more focused description of the DeCaM behind armour debris modeling process.
