Poisson's Ratio Calculator

Poissson's ratio (ν):

Transverse (laterial) strain (ε_transverse):

Axial Strain (ε_axial) (ε):

How This Is Calculated

$$ \nu = -\frac{\epsilon_{transverse}}{\epsilon_{axial}} $$
where:

ν = Poisson's ratio (Dimensionless)

ε_transverse = Transverse (laterial) strain (Dimensionless)

ε_axial = Axial Strain (Dimensionless)

Assumptions

The material behaves according to Hooke's Law.
The materials is homogeneous and isotropic.
The strees applied is uniaxial (applied in only one direction).
The material is pure/ideal.
