The mechanical advancement in conventional origami metamaterials is limited since only single layer exists at a deterministic scale. In this paper, the bio-inspired dual-layer (BDO) proposed, involving couple of nested layers connected by ribs. Sudoku-inspired surrogate models are developed for design parameters to tailor performance BDO. multi-objective optimization reveals that BDO exhibit superior compared with single-layer metamaterial strong interaction between ribs and layers. energy absorption capacity optimal improved 59.45%. Moreover, performance-oriented parameter selection system established, facilitating application wide range protective load-bearing scenarios.

To address the conflict between load conditions and material utilization, natural materials have evolved unique structural strategies exhibiting high mechanical efficiency. Building on hierarchy gradient strategies, current study constructs hybrid hierarchical honeycombs (HHGH), aiming to enhance crashworthiness. Subsequently, impact of each strategy crashworthiness performance is thoroughly investigated. Ultimately, configuration HHGH was optimized by RBF NSGA-II. The results indicate that hybridization various enhancement significantly improves Quantitatively, SEA 2.91 times corresponding regular honeycomb, with similar PCF.

The concept of metamaterial recently emerged as a new frontier scientific research, encompassing physics, materials science and engineering. In broad sense, indicates an engineered material with exotic properties not found in nature, obtained by appropriate architecture either at macro-scale or micro-/nano-scales. metamaterials can be tailored to open unforeseen opportunities for mechanical acoustic applications, demonstrated impressive increasing number studies. Building on this knowledge, theme issue aims gather cutting-edge theoretical, computational experimental studies elastic metamaterials, the purpose offering wide perspective recent achievements future challenges. This article is part ‘Current developments (Part 1)’.
