Poisson’s Ratio calculator

Poisson’s ratio is the ratio of transverse contraction strain to longitudinal extension strain in the direction of the stretching force.

Mathematically, Poisson’s ratio is defined as:

          ν=

Where:

• $\nu$ is Poisson’s ratio,
• Lateral strain is the change in dimension perpendicular to the applied force,
• Longitudinal strain is the change in dimension parallel to the applied force.
