WebbIn materials science and solid mechanics, Poisson's ratio ( nu) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading. The value of Poisson's ratio is the negative of the ratio of transverse strain to axial strain.

The basis of this hypothesis is that weak, porous or dry paste, mortars and concrete will have a low Poisson’s ratio due to the occurrence of plastic deformations and reductions in volume which are more significant than in strong pastes [2]. how it\u0027s made glitter

WebbPoisson's ratio is an elastic constant defined as the ratio of thelateral contraction to the elongation in the infinitesimal uniaxialextension of a homogeneous isotropic body. In a viscoelastic materialPoisson's ratio is a function of time (or frequency) that depends on thetime regime chosen to elicit it. WebbPoisson's ratio (ν) is defined as the ratio of the transverse contraction strain to the longitudinal extension strain in tension. Poisson’s ratio can range from -1 to 0.5 for isotropic materials, but most solids have a positive Poisson’s ratio (0.25-0.33). Negative Poisson’s ratio was initially studied in 2-D structures[1-3].
