A novel design method to produce 3D auxetic metamaterials with continuous pores exemplified through 3D rotating auxetic systems

open access: yesMaterials & Design, 2023
Prototyping of three-dimensional mechanical metamaterials that exhibit negative Poisson’s ratio is usually performed through additive manufacturing. Although this technique has a huge potential, its use to engineer mechanical metamaterials for consumer ...

Multi-step self-guided pathways for shape-changing metamaterials [PDF]

open access: yes, 2018
Multi-step pathways, constituted of a sequence of reconfigurations, are central to a wide variety of natural and man-made systems. Such pathways autonomously execute in self-guided processes such as protein folding and self-assembly, but require external

Enhanced Vibration Isolation with Prestressed Resonant Auxetic Metamaterial [PDF]

open access: yesMaterials, 2021
Metamaterials designate structures with properties exceeding bulk materials. Since the end of the 1990s, they have attracted ever-growing attention in many research fields such as electromagnetics, acoustics, and elastodynamics. This paper presents a numerical and experimental study on a locally resonant auxetic metamaterial for vibration isolation ...

Deep reactive ion etching of auxetic structures: present capabilities and challenges [PDF]

open access: yes, 2014
Auxetic materials (or metamaterials) have negative Poisson ratios (NPR) and display the unexpected properties of lateral expansion when stretched, and equal and opposing densification when compressed. Such auxetic materials are being used more frequently

The structure design and application of metamaterials with negative Poisson's ratio

open access: yesEPJ Applied Metamaterials
Metamaterials with negative Poisson's ratio, also called auxetic metamaterials, are artificially engineered structures or materials that possess extraordinary auxetic effect, high shear modulus, excellent impact resistance, and remarkable energy ...

Deformation of Gels with Spherical Auxetic Inclusions

open access: yesGels, 2022
Auxetic metamaterials possess unnatural properties, such as a negative Poisson’s ratio, which offers interesting features when combined with traditional materials.

Metal-organic framework based on hinged cube tessellation as transformable mechanical metamaterial [PDF]

open access: yes, 2019
Mechanical metamaterials exhibit unusual properties, such as negative Poisson???s ratio, which are difficult to achieve in conventional materials. Rational design of mechanical metamaterials at the microscale is becoming popular partly because of the ...

Auxetic-like metamaterials as novel earthquake protections

open access: yesEPJ Applied Metamaterials, 2015
We propose that wave propagation through a class of mechanical metamaterials opens unprecedented avenues in seismic wave protection based on spectral properties of auxetic-like metamaterials.

A 2D metamaterial with auxetic out-of-plane behavior and non-auxetic in-plane behavior

open access: yes, 2017
Customarily, in-plane auxeticity and synclastic bending behavior (i.e. out-of-plane auxeticity) are not independent, being the latter a manifestation of the former. Basically, this is a feature of three-dimensional bodies.
