Poisson's ratio

n
(General Physics) a measure of the elastic properties of a material expressed as the ratio of the fractional contraction in breadth to the fractional increase in length when the material is stretched. Symbol: μ or ν

1] is a weak function of Poisson's ratio, which is approximated by
M] is the stretch (compression or shear) modulus and viscous parameters and [C] is the Poisson's ratio matrix, respectively.
Those relations are explicitly linear in porosity and implicitly nonlinear through the self-consistent dependence on Poisson's ratio, v, which is itself dependent on porosity.

7[degrees] [8], Young's modulus E = 33 MPa, Poisson's ratio v= 0.
For loading direction 3, the material exhibits a Poisson's ratio close to zero (Fig.
In order to measure the specific elongation of the specimen was used an extension measuring instrument and in order to determine Poisson's ratio was used digital image correlation (DIC) method (Fig.
Poisson's ratio is the worst determined elastic characteristic of all because its influence on the eigenfrequencies of the specimen is sufficiently lower than other elastic characteristics and is difficult to measure by classical tests (Frederiksen 1998).
This equation can also be used for predicting the parameters axial yield strain, lateral yield strain, ultimate lateral strain, Poisson's ratio, lateral dilation ratio, deflection ductility, energy ductility and energy absorption per unit volume.
The UCS and E decrease with increasing grade whereas, according to data by Agapito and Hardy [10], Poisson's ratio (V) shows an increase with grade at room temperature (Figs.
