##### Poisson's ratio - Wikipedia

Know MoreThe Poisson's ratio of a stable, isotropic, linear elastic material must be between −10 and +05 because of the requirement for Young's modulus, the shear modulus and bulk modulus to have positive valu Most materials have Poisson's ratio values ranging between 00 and 05...

## Mesoscale elastic properties of marine sponge spicules ,

Know MoreOn the mesoscopic scale probed by Brillouin scattering, we show that while some properties (Young's moduli, shear moduli, one of the anisotropic Poisson ratios and refractive index) are nearly the same as those of artificial optical fiber, other properties (uniaxial moduli, bulk modulus and a distinctive ,...
