Partially Auxetic Structure of Rotating Rectangles

Applied Sciences
The subject of the analysis is a modified auxetic structure in the form of rotating rectangles, which exhibit large negative Poisson’s ratio values. The structure modification consisted of introducing rotational axes on the surfaces of structural units near the corners of the rectangles.

Ideal isotropic auxetic networks from random networks

, 2019
Auxetic materials are characterized by a negative Poisson's ratio, $\mathrm{\nu}$. As the Poisson's ratio becomes negative and approaches the lower isotropic mechanical limit of $\mathrm{\nu = -1}$, materials show enhanced resistance to impact and shear,
