The influence of magnesium liner on artillery shell explosive disposal

Abstract. In this paper, a numerical simulation model for impact between a magnesium liner and a steel plate was made, in order to study the effect of an ordinance disposal device on an artillery shell. The simulation was made using LS-Dyna software and aim to validate calculations and hypotheses regarding disposal of artillery shells using an explosive device. Geometrical model build in numerical simulation is composed from a cylindrical explosive device and a 9 mm steel plate, which represents the shell body of a medium calibre projectile. Thus, the obtained results shows that although it may represent a laborious study, it serves as a starting point for further research on unexploded ordnance disposal field, a current topic in today's world.
