(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 ...
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 ...
The Poisson ratio (defined as −1 times the ratio of lateral to applied elastic strains) describes the behaviour of stretched materials — positive Poisson ratios characterize the expected normal ...
A group of scientists, including specialists from Landau Institute for Theoretical Physics (ITF), described a universal characteristic, in which many unique graphene properties are "hidden". It turned ...
A car that dashes against an obstacle suffers damages, first to its fenders. There is a keen interest to develop materials that can be sandwiched in the fender system which will absorb the shock and ...
Australia's Defence Science & Technology Organisation (DSTO) has identified a range of aerospace uses for negative Poisson ratio (NPR) materials and recommends further research. NPR materials become ...
