Shear Stress Vs. Normal Stress: Key Differences For …
Poisson's ratio quantifies the relationship between applied stress and the resulting change in material volume. When a material is stretched (or compressed) in one direction, it tends to contract (or expand) in the perpendicular directions. Poisson's ratio captures this behavior by indicating the ratio of lateral strain to longitudinal strain.
