Poisson's Ratio Metals Materials Chart

Strength of Materials  |  Engineering Metals & Materials

The following is a chart of Poisson's Ratio for common engineering materials and metals.

When a compressive force acts on a cylinder body, the force causes the sample to contract in the direction of the force and expand laterally. Within the elastic range of the material, the ratio of these strains is a constant for that particular material. The ratio of the strains, (δ/L) for longitudinal strain and (δ'/r) for lateral strain, is referred to as Poisson's ratio.
