A continuum hyperelastic model for auxetic materials [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 We propose a simple mathematical model to describe isotropic auxetic materials in the framework of the classical theory of nonlinear elasticity. The model is derived from the Blatz–Ko constitutive equation for compressible foams and makes use of a non-monotonic Poisson function.

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

MaterialsFibrous 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.

Auxetic materials : general concepts
, 2013 Auxetic materials are different from other conventional materials since they present a negative Poisson’s ratio. These materials present an unusual behavior: when stretched (elongated in the longitudinal direction), their cross-section is increased.

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.

Hierarchical Fibers with a Negative Poisson’s Ratio for Tougher Composites [PDF]
, 2013 In this paper, a new kind of hierarchical tube with a negative Poisson’s ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb.

A finite element analysis of auxetic composite fabric with rotating square structure
Journal of Industrial Textiles, 2023 The auxetic property of macro-porous rotating square structure has been investigated by many using either experimental or numerical approaches. Given the low breaking strength of the typical rotating square structure, it was proposed to employ an elastic
