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 ...

High-temperature and high-pressure powder X-ray diffraction measurements were conducted at the GSECARS 13-ID-D beamline at the Advanced Photon Source (ANL) using double-sided laser heating, a MARCCD ...

The year is 1981. The scene, the R&D department of a major aircraft company. “Uh, sir?” the young engineer stammers. “Sir? I am concerned about these stiffeners you want to bond onto the skins.” “What ...
