WebVMRs significantly higher than 1 denote a clustered distribution, where random walk is not enough to smother the attractive inter-particle potential. History. The first to discuss the use of a test to detect deviations from a Poisson or binomial distribution appears to have been Lexis in 1877. One of the tests he developed was the Lexis ratio. The Poisson's ratio of a stable, isotropic, linear elastic material must be between −1.0 and +0.5 because of the requirement for Young's modulus, the shear modulus and bulk modulus to have positive values. Most materials have Poisson's ratio values ranging between 0.0 and 0.5.

WebSep 20, 2024 · How can the Poisson’s ratio be greater than 1? We know the Poisson's ratio has a maximum value is 0.5 for elastic material or isotropic material. But for certain types of material that exceed the value of 0.5 also from 1, that type of material is known as an anisotropic material. WebApr 1, 2024 · The Poisson’s ratio is a fixed term, it means the Poisson’s ratio for any material lies between 0 to 1.
