If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

(Nanowerk Spotlight) Poisson's ratio describes the fundamental elasticity of any solid. Conventional materials contract laterally when stretched and Poisson's ratio expresses the ratio of transverse ...

Proceedings of the Royal Irish Academy. Section A: Mathematical and Physical Sciences, Vol. 81A, No. 2 (1981), pp. 147-155 (9 pages) An exact criterion for the number of possible surface waves is ...

This video by ADMET shows a concrete compression test performed according to ASTM C469 - Standard Test Method for Static Modulus of Elasticity and Poisson's Ratio of Concrete in Compression.
