Two‐parameter analysis of auxetics among the cubic crystals is proposed. A brief analysis of the equivalence of this two‐parameter consideration and other approaches is given. The main result of this paper is the classification of partial auxetics with a single dimensionless complex, which is composed of the crystals elastic compliances. The auxetic surface separates the regions with negative and positive Poisson's ratio. The character of its changes with change of the dimensionless complex is… 

Auxetic properties of cubic metal single crystals

The behaviour of the Poisson's ratio is investigated on the basis of derived by the authors explicit equations determining the components of the compliance tensor in an arbitrarily rotated coordinate

Computational prediction of new auxetic materials

TLDR
An approach to screening materials databases for target properties such as negative Poisson’s ratio by using stability and structural motifs to predict new instances of homogenous auxetic behavior as well as a number of materials with near-zero Poisson's ratio is developed.

Experimental study of auxetic behavior of cellular structure

Negative Poisson's ratios as a common feature of cubic metals

Poisson's ratio is, for specified directions, the ratio of a lateral contraction to the longitudinal extension during the stretching of a material. Although a negative Poisson's ratio (that is, a

Poisson’s ratio of anisotropic systems

The Poisson’s ratio of anisotropic materials depends, in general, both on a “longitudinal” direction along which the stress is changed and on a “transverse” direction in which the transverse

Expressions are given for the maximum and minimum values of Poisson's ratio ν for materials with cubic symmetry. Values less than −1 occur if and only if the maximum shear modulus is associated with

Negative Poisson’s Ratios in Anisotropic Linear Elastic Media

Poisson 's ratio for an anisotropic linear elastic material depends on two orthogonal directions n and m. Materials with negative Poisson's ratios for all (n,m) pairs are called completely auxetic
