Engineering Design of a Multiple-Use Spherical Explosion Containment Vessel Subjected to Internal Blast Loading From 25 kg TNT High Explosive

Abstract

Explosion containment vessels have been widely used to contain the internal blast effects. In this paper, we present engineering design and experimental results of a real multiple-use spherical explosion containment vessel, which has been employed to withstand internal blast loading from 25 kg trinitrotoluene (TNT) high explosive in the past 10 years. It is shown that strain growth should be considered in the analysis and design of multiple-use explosion containment vessels, and the dynamic load factor (DLF) method with the consideration of strain growth may achieve a safe and proper design.
