New examples of three-dimensional dilational materials [PDF]
, 2015 Two-dimensional dilational materials, for which the only easy mode of deformation is a dilation are reviewed and connections are drawn between models previously proposed in the literature. Some models which appear to be dilational materials, but which in

Deformation mechanisms leading to auxetic behaviour in the α-cristobalite and α-quartz structures of both silica and germania [PDF]
, 2008 Analytical expressions have been developed in which the elastic behaviour of the α-quartz and α-cristobalite molecular tetrahedral frameworks of both silica and germania are modelled by rotation, or dilation or concurrent rotation and dilation of the ...

Materials & Design, 2018 In this paper, an auxetic cellular structure consisting of re-entrant hexagonal cells have been analyzed, exhibiting different elastic properties in two orthogonal directions.

Universal Negative Poisson Ratio of Self Avoiding Fixed Connectivity Membranes [PDF]
, 2001 We determine the Poisson ratio of self-avoiding fixed-connectivity membranes, modeled as impenetrable plaquettes, to be sigma=-0.37(6), in statistical agreement with the Poisson ratio of phantom fixed-connectivity membranes sigma=-0.32(4).

Fixed-Connectivity Membranes [PDF]
, 2004 The statistical mechanics of flexible surfaces with internal elasticity and shape fluctuations is summarized. Phantom and self-avoiding isotropic and anisotropic membranes are discussed, with emphasis on the universal negative Poisson ratio common to the

Auxetic two-dimensional lattice with Poisson's Ratio arbitrarily close to -1
, 2014 In this paper we propose a new lattice structure having macroscopic Poisson's ratio arbitrarily close to the stability limit -1. We tested experimentally the effective Poisson's ratio of the micro-structured medium; the uniaxial test has been performed ...

, 2015 We formulate a mathematical theory of auxetic behavior based on one-parameter deformations of periodic frameworks. Our approach is purely geometric, relies on the evolution of the periodicity lattice and works in any dimension.

Materials & Design, 2019 In recent years, auxetic cellular materials such as auxetic reentrant honeycombs were widely studied due to its attractively negative Poisson's ratio.

Deformation of Gels with Spherical Auxetic Inclusions
Gels, 2022 Auxetic metamaterials possess unnatural properties, such as a negative Poisson’s ratio, which offers interesting features when combined with traditional materials.

A 2D metamaterial with auxetic out-of-plane behavior and non-auxetic in-plane behavior
, 2017 Customarily, in-plane auxeticity and synclastic bending behavior (i.e. out-of-plane auxeticity) are not independent, being the latter a manifestation of the former. Basically, this is a feature of three-dimensional bodies.
