Definition
Let $B$ be under a force of compression or tension applied longitudinally.
Poisson's ratio is the ratio of the longitudinal strain on $B$ to the lateral strain on $B$.
The validity of the material on this page is questionable. In particular: The link to lateral is to a page which gives a different meaning of "lateral" than is expected here You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by resolving the issues.
