Tunable shape memory auxetics: from 4D printing to numerical simulations

The present work discusses our recent advances on auxetics with tunable shape reconfigurability. To this purpose, 4D printing and multiple shape memory effect are combined. A methodological approach, including a comprehensive experimental and numerical investigation, is proposed. Results are helpful in guiding towards the design of single-material auxetic structures capable of controlled and autonomous in-plane and out-of-plane motions.
