# Auxetic behavior from rotating squares

@article{Grima2000AuxeticBF, title={Auxetic behavior from rotating squares}, author={Joseph N. Grima and Kenneth E. Evans}, journal={Journal of Materials Science Letters}, year={2000}, volume={19}, pages={1563-1565} }

Auxetic materials exhibit the very unusual properties of becoming wider when stretched and narrower when squashed [1], that is they have negative Poisson’s ratios. Apart from the pure scientific interest of having materials showing such an unconventional property, a negative Poisson’s ratio gives a material several other beneficial effects such as an increased shear stiffness, an increased plane strain fracture toughness and an increased indentation resistance. These properties make auxetics…
