Smart Materials and Structures, Год журнала: 2024, Номер 33(4), С. 043002 - 043002

Опубликована: Март 2, 2024

Abstract Structures inspired by the Kresling origami pattern have recently emerged as a foundation for building functional engineering systems with versatile characteristics that target niche applications spanning different technological fields. Their light weight, deployability, modularity, and customizability are few of key continue to drive their implementation in robotics, aerospace structures, metamaterial sensor design, switching, actuation, energy harvesting absorption, wireless communications, among many other examples. This work aims perform systematic review literature assess potential springs structural component design keeping three objectives mind: ( i ) facilitating future research summarizing categorizing current literature, ii identifying shortcomings voids, iii proposing directions fill those voids.

Bandgaps are endowed to elastic metamaterials (EMMs) attributed the rationally designed unit cells and extensive works devoted bandgap enlargement for improving applicability of EMMs in multi-disciplinary applications. Nonetheless, most existing optimization frameworks neglect manufacturing imperfections, such as microscale heterogeneity system uncertainties, which can significantly affect behaviours. Without properly accounting these effects, design may fail achieve optimal goal, exhibiting consistently ultra-wide wave attenuation bands practical EMMs. Herein, this paper, a stochastic framework is developed involving aiming at optimizing first two statistical moments normalized bandwidth (NB) simultaneously. To alleviate large computational costs approximating moments, surrogate model employed reveal constitutive relationship between parameters NB multiscale EMM. Moreover, solve problem effectively efficiently, high-order mutation strategy proposed develop an improved particle swarm (PSO) variant, namely adaptively mutation-based PSO (AHMPSO). demonstrate viability efficiency framework, numerical investigation implemented on 3D EMM, highlights enlarged bandwidths coupling with improvement robustness optimum.

On the reusable compressive behavior of multi-directional auxetic origami metamaterials

Mechanics of Advanced Materials and Structures, Год журнала: 2024, Номер unknown, С. 1 - 15

Origami metamaterials exhibit abnormal mechanical properties through artful structural design. To further explore the behavior of reentrant metamaterials, a multi-directional auxetic origami metamaterial (AOMM) was designed, and its negative Poisson's ratio effect analyzed diagram load bearing deformation. Theoretical models related to geometric parameters, relative density, folding rate, equivalent elasticity plateau were established reveal deformation transformation mechanism, influence size parameters on elastic constants drawn. Using thermoplastic polyurethane (TPU) as substrate, two types AOMMs fabricated by 3D printing, quasi-static compression experiments performed. The results show that TPU has reusable compressive capacity, whose behaviors are mainly contributed buckling instability large sidewall. There is coupling between cross connection boundaries, which in difference AOMM with different sizes. prediction yield strain theories approximate experimental results. Simultaneously, finite element analyses conducted, agrees well experiments. These foundings may provide reference for design application novel or metamaterials.
