When stretching an adhesive specimen along a longitudinal direction, it has a tendency to thin in a lateral direction. Measuring the relationship between how thin a material becomes during stretching ...

(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 ...

In this study, we show that negative Poisson’s ratio is a feature of several metal plates with the nanometer thickness under finite strain, contrasting to their bulk counterparts that exhibit positive ...

This study is led by Prof. Hao Wu (Flexible Electronics Research Center, State Key Laboratory of Intelligent Manufacturing Equipment and Technology, School of Mechanical Science and Engineering, ...

A study compared various artifical intelligence techniques for determining Poisson's ratio and Young's modulus. These techniques provide an alternative, less costly method for determining mechanical ...

When everyday materials are pulled, they stretch or elongate in the direction of the pull and become narrower in cross-section. We can also observe this property in two-dimensional textiles. Auxetic ...

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. Trump slams "troublemakers" after grand ...
