WebbWizard191, the Poisson's ratio has a precisely defined meaning in linear elasticity as a scaling factor for terms in the stiffness tensor. Therefore it is a measure of stiffness though it is dimensionless. The Young's modulus, which is the other stiffness measure in linear elasticity, is also an intensive property. WebbThe range of Poisson's ratio should be between -1.0 to 0.5, because of Young's Modulus, Bulk Modulus, and Shear Modulus requirements. Poisson's ratio of Steel ranges from 0.27 to 0.30. Poisson's ratio of Concrete ranges from 0.20 to 0.25. Example: When a rubber cord is stretched, the change in volume is negligible.
