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.

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 ...

INVESTIGATION OF THE AUXETIC BEHAVIOR OF AN ORIGINAL LATTICE STRUCTURE DESIGN
Gazi Üniversitesi Fen Bilimleri Dergisi, 2023 Auxetic structures are special structures with negative Poisson's ratio due to their geometric shapes in their internal structure. When tensile force is applied to these structures, transverse and longitudinal expansions are observed, while transverse ...

Review of Mechanics and Applications of Auxetic Structures
Advances in Materials Science and Engineering, 2014 One of the important mechanical properties of materials is Poisson’s ratio, which is positive for most of the materials. However, certain materials exhibit “auxetic” properties; that is, they have a negative Poisson’s ratio.
