Poisson’s Ratio is defined as the ratio of the change in the width per unit width of a material, to the change in its length per unit length, as a result of strain.
Poisson’s Ratio is a useful measure of how much a material deforms under stress (stretching or compression). It is important for Mechanical engineering as it allows materials to be chosen that suit the desired function.
The equation for calculating Poisson’s Ratio is given as v= -(ε_trans)/(ε_axil). Transverse strain (ε_strain) is measured in the direction perpendicular to the applied force, and axial strain (ε_axial) is measured in the direction of the applied force.
