The Poisson’s ratio is a fundamental mechanical property that relates the resulting lateral strain to applied axial strain. Although this value can theoretically be negative, it is positive for nearly ...

If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

(Nanowerk Spotlight) Poisson's ratio describes the fundamental elasticity of any solid. Conventional materials contract laterally when stretched and Poisson's ratio expresses the ratio of transverse ...

A group of scientists, including specialists from Landau Institute for Theoretical Physics (ITF), described a universal characteristic, in which many unique graphene properties are "hidden". It turned ...
