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 ...

The publication of Siméon Poisson's Traité de Mécanique in 1811 represented a milestone in our understanding of the properties of materials. Two hundred years on, concepts such as Poisson's ...

A new stretchable substrate has been developed that significantly reduces the Poisson's ratio, minimizing screen distortion and maintaining transparency.

In this video I take a detailed look at Poisson's ratio, a really important material property which helps describe how a material will deform under loading. Wisconsin's attorney general asks the ...
