What is Poisson's Ratio: Poisson's Ratio Formula [PDF ...Poisson’s Ratio is the negative of the ratio of lateral strain ( Transverse) to the linear strain ( Axial). As with the example of a rubber band, when we stretch the length ( Axial), the cross-sectional width gets reduced ( Transverse) and vice versa. The ratio of this change is called Poisson’s ratio. This is named after French engineer Siméon Denis Poisson.

### What is the Poisson ratio of PTFE?

The definition of Poisson ratio contains a minus sign so that normal materials have a positive ratio. At 23 °C, it has a value of 0.46.
