This research investigates the optimization of a multi-material projectile design for perforation of three sequential thin targets. Scalability is investigated through the Buckingham Pi Thereom and a simple geometric scaling method. Altair Hyperworks was used to model the perforation as a two-dimensional plane strain problem and perform the explicit analysis for the impact of the projectile against the target set. Topology optimization was utilized to increase projectile lethality while maintaining stiffness for perforation capability. The two-dimensional results were interpreted to develop a three-dimensional solution that will be additively manu-factured for live fire testing.
