N2 - We designed a novel topologic projectile based on the multiple objective topology optimization method in this study. Topologic and solid 316L stainless steel projectiles were printed in batches in a selective laser melt (SLM) machine. Then the ballistic tests penetrating the Q235 steel target were conducted to evaluate their ballistic performance within a striking velocity range of 300-1000 m/sec. Under a dimensionless specific kinetic energy criterion, topologic projectiles have relatively better penetration capability. Finally, we investigated in detail the failure mechanism of the internal structure of the topologic projectile based on scanning electron microscopy, X-ray micro-CT and explicit dynamics simulation, which can well guide the structural design of the additively manufactured projectiles. The detailed research (full text) has been included in Defence Technology (https://doi.org/10.1016/j.dt.2023.06.010).
