| While traditional or bio-inspired multi-cell structures are widely utilized for crashworthiness applications, this study explores the performance of novel non-closed multi-cell hexagonal columns (NMHCs) with section geometries developed through topology and multi-objective optimizations. Experimental tests, serving as a foundation for validating numerical simulations, were conducted to analyze the behavior of NMHCs under varying loading angles (0°, 10°, and 20°). Four specific configura- tions (II-NMHC1.4–90-20, II-NMHC1.8–90-20, III-NMHC1-90–20, and III-NMHC1.4–90-20) demonstrated progressive deformation under a 20° oblique impact, with thicker walls preferred for II-NMHC and thinner walls for III-NMHC to achieve optimal performance. Notably, SEA for these four columns decreased by an average of 29% under oblique impact, whereas other configurations experienced a 61.5% reduction compared to axial loading. Cell number, load angle, and section geom- etry significantly influenced peak load and specific energy absorption, while wall thickness and diameter primarily affected peak load. Optimization results further highlighted optimal performance at a 10° loading angle across all configurations. The III-NMHC outperformed its peers with identical features, achieving the smallest peak load and highest energy absorption. |
