Poisson’s ratio. This ratio occurs in some of the more complex stress/strain equations. It sounds complicated, but it is simply a way of saying how much the material (taffy) necks down or gets thinner in the middle when it is stretched (Figure 5.10). Its value is most often between.3 and .4 for plastic materials. Check supplier literature
Modulus of elasticity and Poisson's coefficient of polymeric materials. The tables below show the values of Young's modulus (modulus of elasticity) and Poisson's ratio at room temperature for several rigid polymers used in engineering.
In materials science and solid mechanics, Poisson's ratio (symbol: ν ) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading.
24 paź 2011 · Definition and physical significance. Poisson 3 defined the ratio ν between transverse strain (et) and longitudinal strain (el) in the elastic loading direction as ν = − et / el (Box 1).
The Poisson's ratio in viscoelastic materials such as elastomers and many plastics is time dependent in the context of transient tests such as creep and stress relaxation. View chapter Explore book.
Poisson’s Ration. n (for S. Poisson; symbol μ or ν) In a material under tensile stress, the ratio of the transverse contraction to the longitudinal elongation. For metals, Poisson’s ratio is bout 0.3, for concrete, 0.1. For many plastics, the ratio is in the range from 0.32 to 0.48 and for rubbers it is about 0.5.
