Why Poisson’s Ratio Cannot be Greater than 0.5

Theoretically the Poisson ratio should be in between -1 and 0.5 because of the following requirement : the modulus of elasticity (E ), modulus of rigidity (G), and bulk modulus must be positive Now remember the following basic relations of physics : G=E/(2(1+n))………1 K=E/(3(1-2n))……..2 where, n – Poisson’s ratio now from the equation1 it can …
