Auxetic materials, possessing a negative poisson's ratio, can be arranged in various geometric configurations, such as tubular structures. Unlike conventional materials, which contract in lateral dimensions when stretched longitudinally, auxetic tubular expands in response to applied forces. This review article amalgamates the latest experimental data and insights from preceding scholarly works, offering a detailed analysis of the structural design, fabrication processes, and mechanical characteristics of auxetic tubular structures. The review encompasses an analysis of their tensile properties, comparative evaluations with different materials, impact resistance, enhanced bending, and flexibility. Furthermore, the article explores the wide-ranging applications of auxetic tubular in diverse sectors such as automobile manufacturing, aerospace, medicine, and textiles. Additionally, investigated not only new suggestions and future considerations for the advancement of these materials and structures but also a rigorous examination of the forthcoming and new challenges. This multifaceted approach distinguishes it from prior studies within the same scientific domain.

“…Based on this, scholars have continuously proposed novel structures. These structures possess lower peak forces and higher specific energy absorption with stable platform forces [ 4 , 5 ]. Thus, multi-unit column sandwich structures [ 6 , 7 , 8 ], composite structures [ 9 , 10 ], ceramics [ 11 ], gradients [ 12 ], and novel lattices [ 13 , 14 , 15 , 16 , 17 ] have been intensively investigated.…”

Koch Hierarchical Honeycomb: A Fractal-Based Design for Enhanced Mechanical Performance and Energy Absorption

et al. 2023

A novel energy-absorbing structure, the Koch hierarchical honeycomb, which combines the Koch geometry with a conventional honeycomb structure, is proposed in this work. Adopting a hierarchical design concept using Koch has improved the novel structure more than the honeycomb. The mechanical properties of this novel structure under impact loading are studied by finite element simulation and compared with the conventional honeycomb structure. To effectively verify the reliability of the simulation analysis, quasi-static compression experiments were conducted on 3D-printed specimens. The results of the study showed that the first-order Koch hierarchical honeycomb structure increased the specific energy absorption by 27.52% compared to the conventional honeycomb structure. Furthermore, the highest specific energy absorption can be obtained by increasing the hierarchical order to 2. Moreover, the energy absorption of triangular and square hierarchies can be significantly increased. All achievements in this study provide significant guidelines in the reinforcement design of lightweight structures.
