Measurement of Poisson's ratio in the laboratory
As a manufacturer, you want to measure the Poisson's ratio of your materials.
What is the Poisson ratio?
In materials mechanics, the Poisson’s ratio (noted v) is used to measure the contraction of the material perpendicular to the direction of the applied stress. To measure the Poisson’s ratio, the laboratory applies a force to the material to be analysed and measures the elongation in the direction of the force as well as the change in dimension perpendicular to this force. The ratio of these two measurements determines the Poisson’s ratio. It is necessarily between -1 and 0.5, but generally positive.
Why measure the Poisson's ratio?
Measuring the Poisson’s ratio is important for the design of new materials. It allows us to :
