Poisson's ratio is a measure of the Poisson effect, the phenomenon in which a material tends to expand in directions perpendicular to the direction of compression. Conversely, if the material is stretched rather than compressed, it usually tends to contract in the directions transverse to the direction of stretching. It is a common observation when a rubber band is stretched, it becomes noticeably thinner. Again, the Poisson ratio will be the ratio of relative contraction to relative exp… Webb22 sep. 2007 · In a recent paper Kumar et al. [] have reported that for isotropic solid materials Poisson’s ratio decreases with increase in ultrasonic shear wave velocity and suggested a linear relationship between them.Based on Mori-Tanaka mean-field approach, Dunn and Ledbetter [] have shown that for an isotropic porous solid, Poisson’s ratio is a …
