Thin-walled structures are extensively utilized in construction because of their lightweight nature and excellent energy absorption efficiency, especially under dynamic loads. Improving the energy-absorbing performance thin-walled by inspiring natural multi-cell designs is a sufficient approach. This paper investigates characteristics variable novel cross-section subjected to oblique impact loading. Straight tapered types with seven cross-sectional were studied. The nonlinear ABAQUS/Explicit software 6.13 version was implemented analyze crashworthiness behaviors for proposed different loading angles. crushing examined various wall thicknesses 0.5 mm, 1.5 2.5 mm angles 0°, 15°, 30°, 45°. It determined that can be efficiently controlled varying two geometries designs. A multi-criteria decision-making method (MCDM) using complex proportional assessment (COPRAS) performed select optimum shown square structure thickness had best performances (EA) 11.01 kJ specific (SEA) 20.32 kJ/kg 30° angle. Moreover, results indicated EA decreased increase In addition, angle, peak force (PCF) reflected reduction absorbed at larger MCDM conjunction COPRAS proposed; it provides valuable insights safer more resilient building construction.

Sine wave structures have potential applications in anti-collision devices because they reduce the initial peak crushing force (PCF) through active control of folds. However, stability structure during energy absorption needs to be improved. This study proposes a variable-amplitude wave-shaped tube inspired by squid fins at longitudinal direction and horsetail grass transverse direction. Under multidirectional loading quasi-static compression environment, specific capacity (SEA) factor (EASF) squid-fin-horsetail-inspired (SFHT) are evaluated investigating geometrical parameters (inner diameter, wall thickness, number connecting wings, sublayers). The results show that, although folding mechanism characteristic corrugated is changed when tubes reinforced with still ensures reduction PCF. Moreover, performance SFHT improved 170% compared traditional impact box. At same time, SEA optimized sublayers 1, inner diameter 0.5D, wings 6, while EASF stable under multi-directional load. In addition, has better more than other single-core multi-core boxes axial As additive manufacturing technology becomes popular, shows applied automotive systems or similar fields.
