Abstract
This paper examines the macro- and microstructural characteristics of perforating projectiles type Armour Piercing Discarding Sabot (APDS) 20 mm, after being detained by armour plates normally used as defence against projectiles. The effect of impact of these projectiles against high density alumina tiles with several materials of backing plate (steel, alumina and composite) is studied to determine the structural modifications of these projectiles by microhardness and image analysis. The results provide data for studies of simulation of impacts in the design of armour plating.
Kurzfassung
Zur Untersuchung kamen die makro- und mikrostrukturellen Eigenschaften von Durchschlagprojektilen des Typs Armour Piercing Discarding Sabot (APDS) 20 mm nach dem Aufhalten durch Panzerplatten, die normalerweise als Schutz gegen Projektile verwendet werden. Der Effekt des Aufpralls dieser Projektile in hochdichte Aluminiumoxidplatten mit unterschiedlichen Trägerplatten (Stahl, Aluminiumoxid und Verbundmaterial) wurde zur Bestimmung der Gefügeveränderungen dieser Projektile durch Mikrohärtemessung und Bildanalyse untersucht. Die Ergebnisse liefern Daten zur Simulation eines Aufpralls für das Design von Panzerplatten.
