In a new study now published as a report and also illustrated as the online cover-page of Science Advances, Julien Chopin, Arshad Kudrolli, and a research team in Physics in the U.S. and Brazil showed how twisted hyper-elastic sheets formed multi-layered self-scrolled yarns. By incorporating dominant stretching with folding kinematics, they measured torque and energetics originating from geometric nonlinearities. They then introduced a geometric model to explain the formation and structure of such self-scrolled yarns. The outcomes showed how a simple twist of origami in the tensional twist-folding framework led to the transformation of stretchable sheets into self-assembled architectures.
