Poisson s Ratio and Mechanical Nonlinearity Under Tensile

WebPoisson s ratio has a maximum at the onset of strain-hardening and then monotonically decreases with further increase in applied strain. Since the strains in the unnecked region and the necked region are almost constant, the Poisson s ratio during necking is considered to be an averaged Poisson s ratio. http://expresspolymlett.com/articles/EPL-0002245_article.pdf raw edge trousersWebreduces with a high Poisson’s ratio. When the rods are perpendicular to each other, there is no change in the area for small deformations and Poisson’s ratio is 1. However, as the rods are bent with an acuter angle, Poisson’s ratio increases, and the area decreases (Hearle et al., 1969) [3].
