Poisson 39s ratio Wikipedia

Poisson 39s ratio denoted by the Greek letter 39nu ν displaystyle nu nu and named after Siméon Poisson is the negative of the ratio of signed transverse strain to signed axial strain For small values of these changes ν displaystyle nu nu is the amount of transversal expansion divided by the amount of axial
