AbstractA general expression for the directionally anisotropic Poisson's ratio (PR) of cubic materials under external pressure is discussed. It is expressed in terms of the elastic moduli ratios, X = G/K, Y = G/W, where K is the bulk modulus and G, W are shear moduli, and where the mechanical stability criteria are taken into account.

Journal of Materials Science, 2004
Although a negative Poisson's ratio (that is, a lateral extension in response to stretching) is not forbidden by thermodynamics, for almost all common materials the Poisson's ratio is positive. In 1987, Lakes first discovered negative Poisson's ratio effect in polyurethane (PU) foam with re-entrant structures, which was named anti-rubber, auxetic, and ...

Auxetic fibrous materials and structures in medical engineering – a review
Journal of the Textile Institute, 2022Auxetic materials are the materials that expand in the transverse direction when stretched in the longitudinal direction. Auxetics materials are a boon to the field of biomedical engineering, as most of the human tissues have auxeticity.

Auxetic materials: Avoiding the shrink
Nature, 2003Materials that expand laterally when stretched can act as molecular-scale strain amplifiers. This amplification might be exploited in nature and in future technologies.

Two-Dimensional Carbon-Based Auxetic Materials for Broad-Spectrum Metal-Ion Battery Anodes.
Journal of Physical Chemistry Letters, 2019Auxetic materials possess special applications due to their unique negative Poisson's ratios (NPRs). As a classic 2D carbon material, the NPR of graphene is still deliberated.

Mechanical and structure properties of cellular auxetic materials
, 2020Auxetic cellular materials are modern materials which have some unique and superior mechanical properties. As a consequence of the structural deformation of their internal cellular structure they exhibit a negative Poisson's ratio, i.e.
