Abstract

In order to analyze the quality distribution of behind-armor debris and explore the source of debris, experimental and simulation studies on vertical penetration of armor steel by explosively formed penetrator (EFP) were carried out. With the help of experimental and verified simulation methods, the results were analyzed under different target thickness (10- 70 mm) and different EFP target hitting speed (1650m/s~1860m/s). After a typical EFP penetrates armor plate vertically, the quality distribution of target debris produced by EFP is analyzed. The results show that when the EFP’s impact velocity is 1650m/s and the target thickness is between 10mm and 70mm, the proportion of debris with quality less than 1g in the total fragment number decreases with the increase of the target thickness. When the thickness of the target plate is 40mm and the EFP’s impact velocity is between 1650m/s and 1860m/s, the impact velocity has limited influence on the fragment behind the target.
