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 ...
Researchers engineer a new class of microlattice materials with enhanced stiffness-to-density ratios and giant negative Poisson's ratios, ideal for lightweight applications. (Nanowerk Spotlight) ...
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 ...
