# Poisson's ratio and its Range!

v = $$\epsilon$$trans/ $$\epsilon$$axial

where

ν is the resulting Poisson's ratio,
$$\epsilon$$trans is transverse strain
$$\epsilon$$axial is axial strain
and Poissions Ratio have range and its not more then 0.5 and not less then -1?

so my queston is how its value can turn "-1"?

As its already neative and its axial strain or transverse strain one must be negative so the value of Poissions Ratio will turn positive! what do you say!
