Polsson's Ratio

Written by Jerry Ratzlaff on . Posted in Properties

Poisson's ratio is the elastic ratio between lateral strain and longitudinal stress.

Abbreviated as \(Po\)

formula

\(v = \frac { \varepsilon_t } { \varepsilon_a } \)

Where:

\(v\) = Polsson's Ratio

\(\varepsilon_t\) = lateral or transverse strain (direction of load)

\(\varepsilon_a \) = axial or longitudinal strain (right angle to load)
