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

As of 2021, the estimated population of Poissons, France is around 230 people.
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
Les Poissons was created in 1989.
The area of Poissons is 15.48 square kilometers.
Tour Les Poissons was created in 1970.
rubber is the highest; it is nearly incompressible and results in a Poisson ratio approaching 0.5, the highest possible value.
The value of a ratio is the total
La Pêche aux poissons rouges was created in 1895.
There is not a ratio that has the value of one. A ratio is assets over liabilities.
