“…Currently, biologically inspired designs of biomimetic energy-absorbing structures are mainly categorized as lightweight and high-strength structures or hard on its own structures. Designs inspired by lightweight and high-strength biological structures include honeycombs [45], plant stems [46][47][48][49][50][51], bird feather shafts [52,53], insect Wings [54,55], spider webs [56,57], and grapefruit peels [58]. Designs inspired by their own hard biological structures include animal horns [59,60], hooves [61], and bone skins [62], human tibiae [40], bamboo [35,63], conchs [37], mantis shrimp pincers [64], and woodpecker beaks [65].…”

In order to enhance energy absorption, this study draws inspiration from the diagonal bilinear robust square lattice structure found in deep-sea glass sponges, proposing a design for thin-walled structures with superior folding capabilities and high strength-to-weight ratio. Firstly, the crashworthiness of bionic glass sponge tube (BGSTO) is compared with that of equal-wall-thickness equal-mass four-X tube through both experiments and simulations, and it is obtained that the specific energy absorption of BGSTO is increased by 78.64%. And the crashworthiness of BGSTO is also most significant compared to that of multicellular tubes with the similar number of crystalline cells. Additionally, we found that the double-line spacing of the glass sponge can be freely adjusted without changing the material amount. Therefore, based on BGSTO, we designed two other double-line structures, BGSTA and BGSTB. Then with equal wall thickness and mass as a prerequisite, this study proceeds to design and compare the energy absorption properties of three bilinear thin-walled tubes in both axial and lateral cases. The deformation modes and crashworthiness of the three types of tubes with variable bilinear spacing (βO/A/B ) are comparatively analysed. The improved complex proportional assessment (COPRAS) synthesis decision is used to obtain that BGSTO exhibits superior crashworthiness over the remaining two kinds of tubes. Finally, a surrogate model is established to perform multi-objective optimization on the optimal bilinear configuration BGSTO selected by the COPRAS method.

“…Using a surrogate-based multi-objective optimization method that combined polynomial regression and a multi-objective particle swarm optimization algorithm, Huang and Xu [41] optimized the design of an energy absorber that mimics the structure of a marine crustacean known as Odontodactylus Scyllarus. Zhang et al [42] utilized the multi-objective particle swarm optimization algorithm to optimize the energy absorber modeled after the dragonfly wing structure. Fu et al [43] introduced an energy absorber drawing inspiration from bamboo structures and optimized its design by combining the multiobjective particle swarm optimization technique with the response surface method.…”

Throughout evolution, plants and animals have optimized their structure to thrive in a wide range of extreme environments, offering natural structures with both low mass and high energy absorption capacities. Vascular plants have developed a specialized tissue known as the Xylem, which offers structural support and facilitates the transport of water, mineral nutrients, and signals throughout the plant. This study aims to enhance the crashworthiness of vehicles by adapting the Xylem structure to design an effective bioinspired thin-walled structure. Several different crash tube configurations are considered first and their crashworthiness performances are assessed based on two different metrics: specific energy absorption , and crush force efficiency , which are determined by using the Finite Element Analysis (FEA) software LS-DYNA. Then, the crash tube configuration with the best performance is chosen for further investigation. A surrogate-based optimization study is performed, and it is found that and are improved by 151% and 113% compared to an empty circular thin-walled crash tube. Furthermore, the simplified super folding element theory has been used for building a theoretical model that predicts the mean crushing force of the Xylem-mimicking structure. The simulation results and calculated values show a strong agreement, indicating that the proposed theoretical model is of high accuracy.
