Researchers at Vellore Institute of Technology (VIT) in Tamil Nadu, India, found that changing the cell shape of a resin 3D printed auxetic lattice raised its peak load roughly fourfold and its energy ...

Imagine pulling on the long ends of a rectangular piece of rubber. It should become narrower and thinner. But what if it instead became wider and fatter? Now, push in on those same ends. What if the ...

Much like sphere packing, crystalline materials can be similarly described via periodic packing of cylinders in 3D space. In this instance, the cylinders represented rods of strongly bonded atoms or ...

Sandwich structures combining stiff face sheets and lightweight cores have long been valued for their high strength-to-weight ratio and energy absorption capabilities. The incorporation of auxetic ...

I would say the largest man-made auxetic structure I am aware of was probably designed in the 1950s in the case of the graphite core in a number of nuclear reactors. So, on the scale of graphite ...

Researchers replaced the rectangular cross-sections of auxetic honeycomb walls with I-beam profiles, boosting stiffness by ...

As part of research into the development of four-dimensional (4D) printing and active self-deploying structures, scientists from ETH Zurich have proposed a series of 3D printed auxetic meta-materials.

Regardless of whether it is strained or compressed, the new material always expands. Copyright: Thomas Heine et al. Researchers have discovered a two-dimensional ...

Auxetic textiles are materials with a negative Poisson's ratio, expanding laterally when stretched axially. This unique behavior results from molecular reorientation and structural deformations. These ...

One study on using auxetic materials in bra straps found that "auxetic polyester and nylon structures exhibited remarkable pressure distribution capabilities." The design tool devised by the NIST and ...
