Once again, the poor results from this investigation of PP2 indicate that either PP2 is unsuitable for processing via a thermal route to produce an auxetic
polymer or that PP itself is unsuitable.
NPR materials are also called auxetic
, anti-rubber materials.
Since the chiral auxetic
cellular solids are a foam, they are very flexible in volume change and are a good candidate for energy absorption and enhanced protection applications, such as cushioning for helmets, packing materials and sports or military protective armor, the researchers say.
mainly on aerodynamic behaviors rather than its auxetic
The UA Architech is a 360-degree performance training shoe that features a functional 3D printed midsole and 3D ClutchFit auxetic
upper design that creates a 'super-hybrid' trainer.
Moreover, higher Poisson's ratios of insulate coating increase the maximum values of the equivalent stress in each phase and, in the particular case in which the insulated coating is composed of auxetic
material with negative Poisson's ratio, the maximum equivalent stress significantly reduces in each phase.
Equivalent mechanical properties of auxetic
lattices from discrete homogenization.
As the cell topology and constitutive materials are important data, VIPER will consider the combination of different materialsand structural arrangements, in which viscoelastic, poroelastic, auxetic
materials will play a major role.
He includes the latest developmentsufunctionally graded materials, auxetic
materials, shape-memory alloys and smart materials, futuristic plastics, biodegradable composites, and biomimetics, inter alia.
25) Failure of classical elasticity in auxetic
This means that auxetic
materials act as excellent shock absorbers or sponges, a fact that is being explored for various uses.
