Poisson's ratio is an important material property that describes how materials deform when subjected to stress. When a material is stretched in one direction, it tends to contract in the perpendicular ...

Breakthrough study reveals aging skin behaves like a sponge under stress, reshaping our understanding of wrinkle formation.

Why do wrinkles form as we age? A new study has revealed that aging skin stretches more sideways under tension, causing it to ...

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

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 ...

Investigating Poisson’s Ratio of Concrete at Elevated Temperatures Through Non-Destructive Methods They will understand the behavior of concrete under elevated temperatures that is critical for ...
