Can poisson's ratio be greater than 1
WebMar 30, 2016 · For a continuous random variable, the necessary condition is that ∫ R f ( x) d x = 1. Since an integral behaves differently than a sum, it's possible that f ( x) > 1 on a small interval (but the length of this interval shall not exceed 1).

WebJan 27, 2024 · No, Poisson's ratio can not be greater than 1 because it is defined as the ratio of transverse strain to longitudinal strain and these are both positive numbers, so it is always between 0 and 0.5 for most materials. What does the Poisson ratio of 0.5 means? WebApr 26, 2011 · A Poisson's ratio higher would imply a negative lambda coefficient (First Lame coefficient) and a negative dilatation coefficient. It means that your material has a decreasing volume when heated and an increasing volume under pure compressive pression. Both are highly improbable.

WebOct 17, 2015 · Generally we find materials having Poisson's ratio between 0 to 0.5. However some anisotropic materials have Poisson's ratio greater than 0.5 in some directions. Even negative Poisson's ratio values exist in the case of auxetic materials. But we are not going to consider those cases. 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.
