Negative Poisson’s Ratio Materials via Isotropic Interactions [PDF]
Physical Review Letters, 2008 We show that under tension, a classical many-body system with only isotropic pair interactions in a crystalline state can, counterintutively, have a negative Poisson's ratio, or auxetic behavior. We derive the conditions under which the triangular lattice in two dimensions and lattices with cubic symmetry in three dimensions exhibit a negative Poisson ...

A novel mechanical metamaterial with simultaneous stretching- and compression-expanding property
Materials & Design, 2021 Poisson’s ratio is an important property defining the relationship between lateral and longitudinal deformations. While most conventional materials have positive Poisson’s ratios, auxetic metamaterials exhibit negative Poisson’s ratios and will contract ...

Intrinsic Negative Poisson’s Ratio for Single-Layer Graphene [PDF]
Nano Letters, 2016 Negative Poisson's ratio (NPR) materials have drawn significant interest because the enhanced toughness, shear resistance and vibration absorption that typically are seen in auxetic materials may enable a range of novel applications. In this work, we report that single-layer graphene exhibits an intrinsic NPR, which is robust and independent of its ...

Negative poisson’s ratio in single-layer black phosphorus [PDF]
Nature Communications, 2014 The Poisson's ratio is a fundamental mechanical property that relates the resulting lateral strain to applied axial strain. While this value can theoretically be negative, it is positive for nearly all materials, though negative values have been observed in so-called auxetic structures.
