(Of course the opposite phenomenon occurs in a compressed specimen.) The ratio of the transverse strain component to the longitudinal strain component is known as Poisson s ratio. For geometric reasons this ratio must be less than 0.5 in ordinary materials. For incompressible materials (e.g. liquids) Poisson s ratio is 0.5.
