There are some materials with a negative Poissons ratio. Poissons ratio of cork is Poisson's RatioPoisson Ratio of Polymeric Materials. When a material is stretched by a tensile force it usually undergoes a lateral contraction which is known as the Poisson effect. 1 The ratio of the lateral contraction (or compression) and longitudinal extenion is called the Poisson's ratio.. = - lateral / longitudinal. where the minus sign accounts for the negative strain. Poisson's ratio - Simple English Wikipedia, the free Poisson's ratio (letter v) is a measure of the contraction that happens when an object is stretched.This contraction is perpendicular to the stretching force. It can also expand as the object is compressed in a perpendicular direction.
