Poisson’s ratio, ν, is a fundamental mechanical parameter that describes the ratio of the lateral to the longitudinal strain of a material under mechanical load. The precise value of the Poisson’s ...

(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 ...

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 ...
