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 ...

In comparing a material's resistance to distort under mechanical load rather than to alter in volume, Poisson's ratio offers the fundamental metric by which to compare the performance of any material ...

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 ...

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, ...

An understanding of a material's microscopic architecture is important to improve its mechanical properties. Poisson's ratio, which celebrates its bicentenary this year, continues to provide a good ...

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 Debate ...
