Lattice structures are topologically organized porous structures composed of struts meeting at nodes. These structures are of particular interest in materials engineering because of their ability to absorb high energy while maintaining low weight. This work aims to utilize finite element analysis to simulate the ballistic impact of simple cubic lattice structures. It highlights some of the difficulties in such an analysis, such as proper damage evolution and material models, and points to recommendations to continue to improve the model.
