Abstract:This work aims to study the critical initiation conditions of a confined finite‐thickness explosive under jet impact and the influence of shell constraints on the explosive initiation threshold. A theoretical calculation model for jet impact initiation of a confined explosive is established based on the Pop plot of the explosive. A jet impact test is conducted on a confined TNT explosive covered by a 50SiMnVB cover plate by using Φ40 mm shaped charge. A high‐speed camera is utilized to record the reaction proc… Show more
