Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.
the Ppission ratio is: 0.2152 you can refer to this link: http://inmmc.org/ftp/material/silicon-mechanical.html
What is the poission's ratio in machenical structure ?
0.25 to 0.3 depends on the steel
0,32-0,36
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
Poisson ratio of most linear elastic material can be anywhere between 0 and 0.5.
For elastic, isotropic and homogeneous materials, zero Poisson's ratio means that the material doesn't present lateral deformation on bending, compressing or extending.

Poisson's Ratio of stainless steel
For isotropic materials, Rubber - very close to 0.5
Poisson ratio of most linear elastic material can be anywhere between 0 and 0.5.
What is the poission's ratio in machenical structure ?
The bulk modulus (K) is a material's resistance to uniform compression from all directions. If you have Young's Modulus (E) and Poisson's ratio (ν), the relationship is: K = E/(3*(1-2ν)) For E = 220 GPa and ν = 0.29, K = 174.603 GPa

Poisson's Ratio = 0,28
