An Experimental Study of Auxetic Tubular Structures
Materials, 2022 Auxetic tubular structures are widely known structures, characterized by a negative Poisson’s ratio upon stretching and deformation in the axial and transverse directions, which have numerous application possibilities. In this paper, tubular structures were realized by rolling up planar auxetic structures and using rigid square frames as unit cells ...

Hierarchical Fibers with a Negative Poisson’s Ratio for Tougher Composites [PDF]
, 2013 In this paper, a new kind of hierarchical tube with a negative Poisson’s ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb.

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials. [PDF]
Adv Sci (Weinh)This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

A unified design method for 2D auxetic metamaterials based on a minimal auxetic structure
International Journal of Solids and Structures, 2023 Auxetic metamaterials are architected structures that possess a unique property known as a negative Poisson's ratio. This remarkable characteristic enables them to expand or contract in a direction perpendicular to stretch or compression. Due to their exceptional attributes such as energy absorption and fracture resistance, these auxetic metamaterials ...

The Dynamic Stability Problem of Composite Annular Plates with Auxetic Properties
Engineering Transactions, 2023 This paper presents the effect of the auxeticity on the behaviour of a plate subjected to the loss of stability. The plate structure is composed of three layers built of auxetic or conventional facings and a conventional core.
