Experimental evidence of the extent of the plastic flow field in magnesium targets after ballistic impact has been lacking in the previous penetration modeling. The work described in this paper will include the ballistic characterization of the Magnesium alloy AZ31B-H24 in three orientations: normal to the rolling direction; transverse to the rolling; and longitudinal to the rolling direction. Semi-infinite impacts from penetrators in each of the three directions will be shown. The targets were sectioned and machined using electrical discharge machining in preparation for polishing and etching to determine the extent of plastic flow that can be seen. Additionally, the authors plan to conduct micro-hardness analysis to locate the extent of the plastic flow. The authors will investigate the applicability of Effective Flow Stress in the similitude-based empirical model and the Walker-Anderson Penetration Model for small arm penetration prediction. The results will be included in this paper.
