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. ‘Absolutely Failed’: Senators ...

Uniaxial loading. Tensile/compressive stress in the x-direction produces tensile/compressive strain in the x-direction, with the stress and strain related through Young’s modulus E:; Strain in the ...

The Poisson’s ratio measures the length and width of a material undergoing transformation as it is stretched in a longitudinal direction. Application of the ISO 527-2 test standard helps determine the ...

In a paper published in National Science Review, a Chinese team of scientists present a generic strategy to alter the Poisson’s ratio of elastomer membranes. They develop flexible sensors based ...
