Phenolic poisson ratio

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. [3] 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 … 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.
