Nano‐ and Micro‐Auxetic Plasmonic Materials [PDF]

open access: yesAdvanced Materials, 2016
Plasmonic nanostructures with a negative Poisson ratio are demonstrated, having the unusual mechanical property of auxetics to expand laterally when being stretched. Using nanomembrane technology, auxetics are shrunk by orders of magnitude, giving simultaneous access to optical properties of plasmonic metamaterials, as well as auxetic mechanical ...

Onset of criticality in hyper-auxetic polymer networks

open access: yesNature Communications, 2022
Auxetic materials are characterized by a negative Poisson’s ratio - they become thicker when stretched. Here, authors reach the limit of auxetic behavior, known as hyper-auxetic, in polymer networks, hitting an unconventional mechanical critical point.

Elastoplasticity of auxetic materials [PDF]

open access: yesComputational Materials Science, 2012
Abstract Materials exhibiting a negative Poisson’s ratio (auxetics) have drawn attention for the past two decades, especially in the field of lightweight composite structures and cellular media. Studies have shown that auxeticity may result in higher shear modulus, indentation toughness and acoustic damping.

Dynamic behavior and damping capacity of auxetic foam pads [PDF]

open access: yes, 2006
A novel set of auxetic (negative Poisson's ratio) open cell polyurethane foam has been developed and tested under dynamic loading conditions to assess the viscoelastic response under white noise random excitation and compressive cycling.

Auxetic strains—insight from iso-auxetic materials [PDF]

open access: yesMolecular Simulation, 2005
Auxeticity is the result of internal structural degrees of freedom that get in the way of affine deformations. This paper proposes a new understanding of strains in disordered auxetic materials. A class of iso-auxetic structures is identified, which are auxetic structures that are also isostatic, and these are distinguished from conventional elasto ...

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
