thicker and wider. A mechanical strain of 20% would make a part 20% longer, but 6% narrower and thinner, assuming a Poisson’s ratio of 0.3 (typical for most metals).
1) Longitudinal strain is a ratio in the direction of expansion (contraction) of an object. 2) Lateral strain is a ratio of the change in the diameter direction. The ratio between longitudinal and lateral strains is called the “Poisson’s ratio,” and general metallic materials have a ratio...
Patient consent was waived due to a retrospective study using de-identified clinical data that was obtained after approval from the institution’s IRB. Since all information was anonymous and does not impact patients in any way, no patient consent was required. ...
Two members of this family that will be of particular interest to us are the Poisson and negative binomial distributions, which are commonly encountered in the modelling of counts and the possibility of over-dispersion. The probability mass functions (pmfs) of these distributions are the form: p...
Poisson's ratio is used in more complicated ways in several fields of science. When you bend an object in one direction, Poisson's ratio affects the way the object curves in the perpendicular direction. The ratio also affects the way stress waves travel through substances such as rock, meanin...
