Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

On the Origins of Out‐of‐Plane Auxetic Response in Paper

physica status solidi (b), EarlyView.
Paper can be auxetic! Paper can exhibit a range of out‐of‐plane Poisson's ratio (PR) values. Examining handsheets made from hardwood (HW) and softwood (SW) fibers, of a variety of weights (1, 3, or 5 g) and refining degrees (none, R, or R+), showed that the sign and magnitude of PR can be finely controlled by modifying network parameters.

Anticlastic Curvature and Material Freedom

physica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Parametric optimization of selected auxetic structures

Multiscale and Multidisciplinary Modeling, Experiments and Design
AbstractAuxetic materials exhibit an interesting, counterintuitive behavior—when subjected to uniaxial tension, they stretch laterally, and when uniaxially compressed, they shrink laterally. In contrast to conventional materials, in auxetics, the value of Poisson’s ratio is negative.

Negative Stiffness Induced and Controlled by Constriction

physica status solidi (b), EarlyView.
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).
