Poisson's Ratio Calculator

Poisson's ratio ν = −ε_lateral / ε_axial.

Lateral strain

Axial strain

Poisson's ratio ν

How it works

Poisson's ratio relates lateral contraction to axial extension under load.

Negate the ratio of lateral strain to axial strain.

\[ \nu = -\frac{\varepsilon_{\perp}}{\varepsilon_{\parallel}} \]
