TLDR
On the bicentenary of the publication of Poisson's Traité de Mécanique, the continuing relevance of Poissons's ratio in the understanding of the mechanical characteristics of modern materials is reviewed.Abstract:
In comparing a material's resistance to distort under mechanical load rather than to alter in volume, Poisson's ratio offers the fundamental metric by which to compare the performance of any material when strained elastically. The numerical limits are set by ½ and -1, between which all stable isotropic materials are found. With new experiments, computational methods and routes to materials synthesis, we assess what Poisson's ratio means in the contemporary understanding of the mechanical characteristics of modern materials. Central to these recent advances, we emphasize the significance of relationships outside the elastic limit between Poisson's ratio and densification, connectivity, ductility and the toughness of solids; and their association with the dynamic properties of the liquids from which they were condensed and into which they melt.read more

Shear bands in metallic glasses
TL;DR: A comprehensive and up-to-date review on the rapid progress achieved very recently on this subject can be found in this article, where key materials-science issues of general interest, including the initiation of shear localization starting from shear transformations, the temperature and velocity reached in the propagating or sliding band, the structural evolution inside the shear-band material, and the parameters that strongly influence shearbanding are discussed.

Penta-graphene: A new carbon allotrope
Shunhong Zhang,Shunhong Zhang,Shunhong Zhang,Jian Zhou,Qian Wang,Qian Wang,Qian Wang,Xiaoshuang Chen,Xiaoshuang Chen,Yoshiyuki Kawazoe,Puru Jena +10 more
TL;DR: It is shown that penta-graphene, composed of only carbon pentagons and resembling Cairo pentagonal tiling, is dynamically, thermally, and mechanically stable, and exhibits negative Poisson's ratio, a large band gap, and an ultrahigh mechanical strength.

Negative poisson’s ratio in single-layer black phosphorus
Jin-Wu Jiang,Harold S. Park +1 more
TL;DR: This work reports using first-principles calculations the existence of a negative Poisson's ratio in a single-layer, two-dimensional material, black phosphorus, and originates from its puckered structure, where the pucker can be regarded as a re-entrant structure that is comprised of two coupled orthogonal hinges.
