Potential and applications of auxetic tubular: a review

Abstract

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.

Quasi-static crashworthiness behaviour of auxetic tubular structures based on rotating deformation mechanism

“…These structures have been extensively studied and developed in both 2D and 3D forms, with a shift towards 3D microstructural design to improve the accuracy of predicting auxetic behaviour [29,30]. Tubular structures, a type of 3D structure, are of great importance in many applications, particularly as widely used mechanical components and structures in engineering fields [31]. The cross-sectional form of tubular can vary in a wide range of possibilities, but the most prevalent configuration is the circular shape [32].…”
