Automatic design of reversible shape changing metamaterials — Silvia Bonfanti, Francesc Font Clos, Roberto Guerra, and •Stefano Zapperi — University of Milan, Milan, Italy

We have developed a computational method to design metamaterials that perform pre-determined input/output mechanical operations. Our numerical scheme to design metamaterials combines a reinforced dynamic Monte Carlo method with finite element simulations. We performed 3D printing of selected metamaterial configurations, showing that the machine-generated solutions present effciencies far exceeding those of man-designed ones. Finally, we show that machine learning algorithms can be trained to identify efficient solutions without performing simulations. The designed metamaterial units can be exploited as the building blocks of generic metamaterial machines or other actuators with higher complexity.
