Poisson’s Ratio (symbolized as ν or μ) is a material property that describes the ratio of lateral or transverse strain (strain in the direction perpendicular to an applied force) to axial or longitudinal strain (strain in the direction of the applied force) in a material when it’s subjected to an external force. It’s important in
