Poisson's ratio of a material defines the ratio of transverse strain (x direction) to the axial strain (y direction)In materials science and solid mechanics, Poisson's ratio (symbol: ν ()) is a measure of the Poisson effect, the deformation (expansion or contraction) of a material in directions perpendicular to the specific direction of loading.
Conversely, if the "integrated" Poisson's ratio is constant, which is what you are talking about, then the incremental Poisson's ratio must vary with the amount of deformation. Only when the deformations are very small with respect to the dimensions of the unstressed test object do the two become very nearly the same.

Islam counsels its followers to abstain from both these paths of extremities and adopt moderation in chasing the world and practicing religion alike. Not the least the Quran emphasises that the Muslim community (Umma) is a ’middle nation’ / a 'just community' / an Umma justly balanced / a moderate nation / a midmost nation (ummatan wasaTan ...
Poisson number can refer to: In mechanics, the reciprocal of Poisson's ratio. 1 / v. In statistics, a number drawn from a Poisson distribution
Unsurprisingly, the issue of Islam as state religion divides the Muslim and non-Muslims with a contrasting 85% supporting and opposing, respectively. Nevertheless, 93% of Sarawakians consider their regional Sarawak identity to be their first choice in defining themselves which is in stark contrast to Peninsular Malaysia where 55% see religion ...
In probability theory and statistics, the Poisson distribution (/ ˈ p w ɑː s ɒ n /) is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event.

A Poisson regression model is sometimes known as a log-linear model, especially when used to model contingency tables. Negative binomial regression is a popular generalization of Poisson regression because it loosens the highly restrictive assumption that the variance is equal to the mean made by the Poisson model. The traditional negative ...
