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 ...

Consider the animation below of such a material, and study how a negative value for Poisson’s ratio is possible with this material. As can be seen here, a compressive axial load produces contraction ...

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 ...

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 ...

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 ...
