Poisson's Ratio
Poisson's Ratio is a measure of how a material deforms when stretched or compressed. Specifically, it describes the relationship between the change in length along one direction and the change in width or height in the perpendicular direction. For instance, when you stretch a rubber band, it becomes thinner in the middle. Poisson's Ratio quantifies this effect, showing how much a material expands or contracts in dimensions not directly affected by stress. A value close to 0 means little change in the other dimensions, while values closer to 0.5 indicate more significant deformation.

Poisson's ratio is a measure of how a material deforms when it is stretched or compressed. Specifically, it describes the relationship between the change in length (strain) in one direction and the change in size (strain) in the perpendicular direction. If you stretch a rubber band, it gets thinner; Poisson's ratio quantifies this effect. A value of 0 means no thinning, while values closer to 0.5 indicate that the material exhibits significant lateral contraction when extended. This property is important in fields like engineering and materials science, helping to predict how materials will behave under different stress conditions.
