Poisson's Ratio Calculator
Calculate material Poisson's ratio using transverse and axial strains
Formula: $\nu = -\frac{\varepsilon_{trans}}{\varepsilon_{axial}}$
Where $\nu$ is Poisson's ratio, $\varepsilon_{trans}$ is transverse (lateral) strain, and $\varepsilon_{axial}$ is axial (longitudinal) strain.
Where $\nu$ is Poisson's ratio, $\varepsilon_{trans}$ is transverse (lateral) strain, and $\varepsilon_{axial}$ is axial (longitudinal) strain.
