Poisson's ratio is the negative ratio of how compression affects distortion. When an object is compressed in one direction it expands in two directions perpendicular to the direction of compression. The ratio is equal to d(transverse strain)/d(axial strain).

K=E/(3*(1-2v)) K: Bulk modulus E: young modulus v: poison's ratio on the other hand: delta V/V=(1-2v)*delta L/L relative change in Volume equals to: (1-2v) * relative change in length.
For isotropic materials, Rubber - very close to 0.5
between .15 and .20
since k=E/3(1-2n): where k=bulk modulus and n=poision's ratio it can be seen that value of poision's ratio can't be smaller than 0.5 in order to keep k be +ve.hence poision's ratio is 0.5
The Poisson's ratio of teak wood typically ranges from about 0.3 to 0.4. This ratio indicates the relationship between the longitudinal strain and the lateral strain experienced by the wood when subjected to stress. Variations in the value can occur due to factors like moisture content, density, and the specific growth conditions of the wood.

Poisson's ratio is 0.3 for metals because the metals begin to get thinner the more they are stretched. It also relates a strain that is tensile to a strain that is compressive.Ê
As of 2021, the estimated population of Poissons, France is around 230 people.
Les Poissons was created in 1989.
The area of Poissons is 15.48 square kilometers.
rubber is the highest; it is nearly incompressible and results in a Poisson ratio approaching 0.5, the highest possible value.
Tour Les Poissons was created in 1970.
