Question

What is poisson's ratio?

Answer 1

Poisson's ratio:

1. The ratio of transverse contraction strain to longitudinal extension strain in the direction of stretching force is known as Poisson's ratio.
2. Tensile deformation is regarded as positive, whereas compressive deformation is regarded as negative.
3. Because the definition of Poisson's ratio includes a minus sign, normal materials have a positive ratio.
4. Poisson's ratio, also known as the Poisson coefficient or coefficient de Poisson, is typically represented as a lower case Greek nu v.
