Energy Absorption Performance of Bio-inspired Honeycombs: Numerical and Theoretical Analysis

Abstract Energy absorption performance has been a long-pursued research topic in designing desired materials and structures subject to external dynamic loading. Inspired by natural bio-structures, herein, we develop both numerical theoretical models analyze the energy behaviors of Weaire, Floret, Kagome-shaped thin-walled structures. We demonstrate that these bio-inspired possess superior capabilities compared traditional structures, with specific about 44% higher than honeycomb. The developed mechanical model captures fundamental characteristics honeycomb, mean crushing force all three is accurately predicted. Results indicate although basic deformation mode remain same, varied geometry design corresponding material distribution can further boost structure, providing much broader space for next-generation impact systems.
