WebYoung’s modulus, the shear modulus, and the bulk modulus are related to Poisson’s ratio. For these modules to have positive values, the Poisson’s ratio of a stable, isotropic, linear elastic material must be between −1.0 and +0.5. The value of Poisson’s ratio normally ranges between 0.0 and 0.5.
