Poisson material
WebMay 13, 2024 · A Poisson distribution is a discrete probability distribution. It gives the probability of an event happening a certain number of times ( k) within a given interval of time or space. The Poisson distribution has … In materials science and solid mechanics, Poisson's ratio (nu) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading. The value of Poisson's ratio is the negative of the ratio of transverse strain to axial strain. For small values of these changes, is the amount of transversal elongation divided …
