POISSON'S RATIO CHART FOR METALS AND MATERIALS


Room temperature Poisson's ratios for materials including concrete, aluminum alloys, copper alloys, cast irons,  steel alloys and titanium alloys are given in the following chart.

Poisson's ratio is the negative ratio of lateral strain to longitudinal strain for given material subjected to uniform longitudinal stress within the elastic deformation range. Poisson's ratio values for many metals and alloys range between 0.25 to 0.35. Poisson's ratio is an important design parameter which is needed for strength of materials calculations of metals.
