Can poisson's ratio be greater than 1
Did you know?
The Poisson's ratio of a stable, isotropic, linear elastic material must be between −1.0 and +0.5 because of the requirement for Young's modulus, the shear modulus and bulk modulus to have positive values. Most materials have Poisson's ratio values ranging between 0.0 and 0.5. See more In materials science and solid mechanics, Poisson's ratio $${\displaystyle \nu }$$ (nu) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of See more Length change For a cube stretched in the x-direction (see Figure 1) with a length increase of $${\displaystyle \Delta L}$$ in the x direction, and a length decrease of $${\displaystyle \Delta L'}$$ in the y and z directions, the … See more Negative Poisson's ratio materials Some materials known as auxetic materials display a negative Poisson's ratio. When subjected to … See more One area in which Poisson's effect has a considerable influence is in pressurized pipe flow. When the air or liquid inside a pipe is highly … See more Poisson's ratio is a measure of the Poisson effect, the phenomenon in which a material tends to expand in directions perpendicular to the direction of compression. Conversely, if the material is stretched rather than compressed, it usually tends to … See more Isotropic For a linear isotropic material subjected only to compressive (i.e. normal) forces, the deformation of a material in the direction of one … See more At finite strains, the relationship between the transverse and axial strains $${\displaystyle \varepsilon _{\text{trans}}}$$ See more http://glassproperties.com/poisson_ratio/
