On the origin of negative Poisson’s ratio in buckypapers
Extreme Mechanics Letters, 2021Unprecedented sign change of Poisson's ratio not only paves the way for diverse applications, but it provides a sense of deep understanding of ‘hidden’ mechanics, yet to be discovered. Stochastically distributed multi-walled carbon nanotubes in the form of buckypaper can possess negative Poisson's ratio, but the underlying design principles are still ...

Negative Poisson's ratio in rippled graphene
Nanoscale, 2017In this work, we perform molecular dynamics (MD) simulations to study the effect of rippling on the Poisson's ratio of graphene. Due to the atomic scale thickness of graphene, out-of-plane ripples are generated in free standing graphene with topological defects (e.g. heptagons and pentagons) to release the in-plane deformation energy.

Negative Poisson's ratio in graphene oxide
Nanoscale, 2017We perform molecular dynamics simulations to investigate the Poisson's ratio of graphene oxide. We find that the Poisson's ratio can be effectively tuned by increasing the degree of oxidation of graphene oxide. More specifically, the Poisson's ratio decreases linearly from positive to negative with increasing oxidation, turning negative at room ...

Nonlinear Analysis of the Poisson's Ratio of Negative Poisson's Ratio Foams
Journal of Composite Materials, 1995This article contains an analytic study of Poisson's ratio of re-entrant foam materials with negative Poisson's ratio. These materials get fatter when stretched and thinner when compressed. The Poisson effect is so fundamentally important to the properties of a material that a large change in the value of the ratio will have significant effects on the ...

3D Soft Metamaterials with Negative Poisson's Ratio
Advanced Materials, 2013Buckling is exploited to design a new class of three-dimensional metamaterials with negative Poisson's ratio. A library of auxetic building blocks is identified and procedures are defined to guide their selection and assembly. The auxetic properties of these materials are demonstrated both through experiments and finite element simulations and exhibit ...

On the negative Poisson’s ratio of an orthorhombic alloy
Scripta Materialia, 2003Abstract The existence of the counterintuitive property for which a material laterally expands when stretched, is described with reference to the orthorhombic CuAlNi alloy. In particular, it is shown that there is a set of planes for which Poisson’s ratio is always negative.

Negative Poisson's Ratios for Extreme States of Matter
Science, 2000Negative Poisson's ratios are predicted for body-centered-cubic phases that likely exist in white dwarf cores and neutron star outer crusts, as well as those found for vacuumlike ion crystals, plasma dust crystals, and colloidal crystals (including certain virus crystals).

Foam Structures with a Negative Poisson's Ratio
Science, 1987A novel foam structure is presented, which exhibits a negative Poisson's ratio. Such a material expands laterally when stretched, in contrast to ordinary materials.
