In materials science and solid mechanics, Poisson's ratio (nu) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading. The value of Poisson's ratio is the negative of the ratio of transverse strain to axial strain. For small values of these changes, is the amount of transversal elongation divided … WebThe value of the Poisson ratio for stable, isotropic materials should lie between -1.0 to 0.5 because it has a direct impact on the Young Modulus, Bulk Modulus, and Shear modulus value.
