چکیده مقاله
With the rapid advancement of additive manufacturing AM technologies, the fabrication of lightweight lattice structures with complex geometries and enhanced mechanical performance has become increasingly feasible This study presents the design and numerical analysis of a novel bioinspired lattice structure derived from the morphology of butterfly wings, aiming to improve energy absorption capabilities Two thermoplastic materials, PLA and ABS, were employed to fabricate the structures using 3D printing, resulting in two configurations: BWP PLA based and BWA ABS based Finite element simulations were conducted in Abaqus/Explicit to evaluate the compressive behavior and energy absorption performance of the designs The results, presented through force displacement curves and deformation patterns, revealed that while the BWA structure exhibited higher load bearing capacity up to 100 kN , the BWP structure demonstrated superior energy absorption metrics, including higher EA, SEA, and EAE values Given the importance of specific energy absorption SEA in impact related applications, the BWP structure is identified as the optimal design for use in energy absorbing components such as crash boxes and protective systems
