Definition of Poisson's ratio

Poisson's ratio is the ratio of transverse contraction strain to longitudinal extension strain in the direction of stretching force. Tensile deformation is considered positive and compressive deformation is considered negative. The definition of Poisson's ratio contains a minus sign so that normal materials have a positive ratio. Poisson's ratio, also called Poisson ratio or the Poisson coefficient, is usually represented as a lower case Greek nu, n.

If your browser does not internet Symbol font properly, Greek nu, n may instead look like a bold face Latin n.
