In this paper we probe the effect of a bullet's jacket on its ability to enhance penetration of a bullet core into a ceramic-faced target. This is achieved through computational modelling using ANSYS AUTODYN® and by Split-Hopkinson Pressure-Bar compression testing of a core, with and without a jacket. The focus of this work was on an AK47 mild-steel-cored (MSC) bullet. The objective of this work was to investigate the role of the jacket in the penetration process and to better understand if there is any protective benefit of stripping a bullet's jacket prior to making contact with ceramic armour. Further, new Johnson-Cook parameters for the AK47 steel core are presented.
