| dc.description.abstract | This study examines the design, fabrication, and mechanical performance of maraging steel BCCZ microlattices produced using Laser Powder Bed Fusion (LPBF) for energy absorption applications. Four lattice structures—rigid plate (RP), full strut plate (FSP), half strut plate (HSP), and parallel strut plate (PSP)—were analyzed for their compressive properties through uniaxial testing and finite element simulations using ABAQUS. The impact of plate configurations on mechanical behavior was evaluated, with simulation results calibrated and validated against experimental data, showing a deviation of only 1.1% in energy absorption. Among the designs, the rigid plate structure exhibited superior energy absorption capabilities in simulations, warranting further investigation of this design with one and three plates. These findings provide valuable insights into optimizing microlattice structures for improved mechanical performance, highlighting their potential in advanced energy absorption applications in additive manufacturing. | |
