Periodic Auxetics: Structure and Design [PDF]
The Quarterly Journal of Mechanics and Applied Mathematics, 2017 Materials science has adopted the term of auxetic behavior for structural deformations where stretching in some direction entails lateral widening, rather than lateral shrinking. Most studies, in the last three decades, have explored repetitive or cellular structures and used the notion of negative Poisson's ratio as the hallmark of auxetic behavior ...

Virtual and Physical Prototyping, 2023 A novel type of tubular structure with negative Poisson's ratio based on gyroid-type triply periodic minimal surfaces (TPMSs) is proposed in this study. This work is an attempt to design auxetic tubular structures based on TPMS.

Machine learning accelerated design of auxetic structures
Materials & Design, 2023 Auxetic metamaterials exhibit unusual expansion perpendicular to the direction of tensile loading, a behavior known as negative Poisson's ratio (NPR). The microstructures of auxetic metamaterials require rational design.

Materials & Design, 2020 It was supposed that auxetic structure with negative Poisson's ratio (NPR) expands under stretch and could enhance the screw-bone fixation. In this study, the novel auxetic structure based bone screws were designed, and mechanical properties and fixation

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 ...

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.
