A comparison of behind-armour debris recording and analysis techniques: flash radiography and witness packs
conference paper
Behind-armour (BA) debris is a dominating component damage mechanism encountered within land, air and sea vehicles. Its importance in relation to vulnerability/lethality (V/L) modeling is increasing. Consequently, an accurate determination of BA debris velocity and mass is imperative for the acquisition of reliable and reproducible data. Two BA debris recording techniques are presently used throughout the defence research community: flash radiography and witness packs. The first is presently used at the TNO/Prins Maurits Laboratory in the Netherlands whereas the Jatter is extensively used at DRE Valcartier in Canada. The paper presents a summary of both techniques and the results obtained for the computation of fragment velocity and mass. An experimental test was designed to allow both flash radiography and witness packs to be used simultaneously and to allow recovery of real fragments for comparison. Although the mass is overestimated in both cases, system improvements are currently underway.
