This article explains the auxetic behavior of a liquid crystalline elastomer, which occurs at molecular level, by deducing strain-induced changes in order parameters and interpreting them as out-of-plane rotations molecules.

Auxetic fabrics are those with a negative Poisson's ratio and have received increasing attention in recent years. In our previous study, series of auxetic warp‐knitted were developed based on re‐entrant geometry their effects experimentally investigated. Unlike weft‐knitted fabrics, the preparation production process very complicated time consuming. However, finite element (FE) method offers an...

There is increasing interest in two-dimensional and quasi-two-dimensional materials metamaterials for applications chemistry, physics engineering. Some of these are driven by the possible auxetic properties such materials. Auxetic frameworks expand along one direction when subjected to a perpendicular stretching force. An equiauxetic framework has unique mechanism expansion (an mode) where symm...
