Abstract
This memorandum presents a linear approach to resolve the uncertainties associated with the fragment penetration holes which coalesce to form a large hole on the first plate of a witness pack used in the recording of behind-armour debris. Also, a new correction equation is applied to define the fragment-projected area for each hole recorded in the witness pack and finally, a virtual characterization plan concept in this document were performed with the latest versions of DeCaM (Debris Characterization and Modelling software) and WPAS (Witness Pack Analysis System). Experimental results show the validity of a linear approach for the small calibre ammunition studied with a single target plate. Impact with medium calibre ammunition and a multi-plate target however, illustrate a more complex behaviour. Finally, the benefits of the new correction equation on the fragment mass and velocity calculation as well as the virtual characterization plan concept are presented.
