Computational prediction of new auxetic materials [PDF]
Nature Communications, 2017 There are very few inorganic materials with auxetic homogenous Poisson’s ratio in polycrystalline form. Here authors develop an approach to screening materials databases for target properties such as negative Poisson’s ratio by using stability and ...

Theory of strains in auxetic materials [PDF]
Journal of Superconductivity and Novel Magnetism, 2012 Auxetic materials, or negative-Poisson's-ratio materials, are important technologically and fascinating theoretically. When loaded by external stresses, their internal strains are governed by correlated motion of internal structural degrees of freedom ...

A mechatronic shape display based on auxetic materials. [PDF]
Nat Commun, 2021 AbstractShape displays enable people to touch simulated surfaces. A common architecture of such devices uses a mechatronic pin-matrix. Besides their complexity and high cost, these matrix displays suffer from sharp edges due to the discreet representation which reduces their ability to render a large continuous surface when sliding the hand. We propose

Auxetic metamaterials subjected to dynamic loadings [PDF]
Theoretical and Applied Mechanics, 2022 Materials with negative Poisson’s ratio are called auxetics and they present enhanced properties (e.g. damping, indentation resistance, fracture toughness and impact resistance) under external loadings.

Extreme Behaviors in Fibrous Material Remodeling: Auxetic to Non-Auxetic Transition and Phase Segregation. [PDF]
Materials (Basel)Fibrous materials, prevalent in biological tissues and engineered composites, undergo remodeling in response to mechanical loads, leading to plastic changes in fiber orientation. A previously developed continuum model describes this remodeling process.

Compressive mechanical properties of ex-situ auxetic composite-filled tubes
Journal of Materials Research and Technology, 2021 Auxetic materials are a class of materials that expand transversely when stretched longitudinally. Recently, auxetic materials are gaining special interest in wide range of applications mainly due to their attractive mechanical behavior.

Progress of auxetic and semi-auxetic materials
Engineering review, 2023 Auxetic materials with negative Poisson's ratios, display the unique behavior owing to their micro-structure or geometrical build. Auxetic materials resist deformities when subjected to uniaxial, biaxial, and shearing stresses. Cellular based materials are known for their excellent impact and shock energy absorption.
