Finding Young's Modulus and Poisson's Ratio

The Poisson ratio for most metals falls between 0.25 to 0.35. Rubber has a Poisson ratio close to 0.5 and is therefore almost incompressible. Theoretical materials with a Poisson ratio of exactly 0.5 are truly incompressible since the sum of all their strains leads to a zero volume change.
