Auxetic nanomechanical metamaterials
, 2015 Metamaterials derive unique optical properties from artificial structuring of plasmonic materials, while auxetics consist of artificial reconfigurable structures causing them to exhibit unique mechanical properties. In particular, auxetics possess a negative Poisson’s ratio - that is a unique mechanical property causing them to expand laterally upon ...

Mechanical Metamaterials: Auxetic Metamaterials
Metamaterials are a type of artificial material with microstructural features that are characterized by physical properties not found in nature. Metamaterials originated in the field of electromagnetics and have now blossomed in fields such as acoustics, mechanics and optics.

Auxetic Two‐Phase Chevron Mechanical Metamaterial
Advanced Engineering MaterialsThis investigation explores novel two‐phase chevron mechanical metamaterials that exhibit auxetic properties. Unlike traditional foam‐like cellular or porous auxetic materials, these designs are composed of chevron patterned layers embedded in anisotropic matrix.

From Geometric Transformations to Auxetic Metamaterials
Computers, Materials & Continua, 2014 The paper introduces a new alternative towards fabrication of auxetic metamaterials (materials with negative Poisson’s ratio) controlled by geometric transformations. These transformations are derived from the theory of small (infinitesimal) elastic deformation superimposed on finite elastic deformations.

Origami-inspired deployable auxetic metamaterials
, 2014 Developing complex spatial objects from a flat sheet of material using origami folding techniques has long attracted attention in science and engineering. Recent research has shown that in origami-based deployable folded sheet materials, such as Miura-ori, metamaterial properties of the patterns are basically because of their folding geometry [1, 2 ...

Transforming Auxetic Metamaterials into Superhydrophobic Surfaces
Small StructuresSuperhydrophobic materials are often inspired by nature, whereas metamaterials are engineered to have properties not usually occurring naturally. In both, the key to their unique properties is structure. Here, it is shown that a negative Poisson's ratio (auxetic) mechanical metamaterial can transform into a unique superhydrophobic material.
