Dynamic Behavior of Aluminum Plates Subjected to Sequential Fragment Impact and Blast Loading: An Experimental Study

This paper presents a study on the dynamic behavior of thin aluminum plates subjected to consecutive fragment impact and blast loading. To this end, two separate experimental setups are used. In first setup, 2 mm thick EN-AW-1050A-H24 were ballistic fragment-simulating projectiles (FSPs). Experiments carried out for FSP calibers 7.62 12.7 considering both single triple impacts with variations in spacing locations. The out-of-plane displacement in-plane strain fields measured using digital image correlation (DIC) coupled pair high-speed cameras stereoscopic setup. second subsequent loading was applied perforated an explosive-driven shock tube (EDST). After perforated, field around holes depended caliber, orientation FSP, distance between When applied, cracks tended appear areas concentration holes. It found that relative significantly influences target’s response mode.
