# A 2D microstructure with auxetic out-of-plane behavior and non-auxetic in-plane behavior

@article{Davini2017A2M, title={A 2D microstructure with auxetic out-of-plane behavior and non-auxetic in-plane behavior}, author={C. Davini and A. Favata and A. Micheletti and R. Paroni}, journal={Smart Materials and Structures}, year={2017}, volume={26}, pages={125007} }

Customarily, in-plane auxeticity and synclastic bending behavior (i.e. out-of-plane auxeticity) are not independent, being the latter a manifestation of the former. Basically, this is a feature of three-dimensional bodies. At variance, two-dimensional bodies have more freedom to deform than three-dimensional ones. Here, we exploit this peculiarity and propose a two-dimensional honeycomb microstructure with out-of-plane auxetic behavior opposite to the in-plane one. With a suitable choice of the… Expand
