Rigidity control of general origami structures (opens in new tab)

Origami has inspired the modern design of flexible structures in science and engineering. However, the rigidity control of general origami structures beyond the well-studied Miura-ori pattern remains unclear. Here we show that the rigidity of a wide range of origami structures can be controlled by enforcing or relaxing the planarity condition of selected facets. Through numerical simulations on origami structures with different facet selection rules, we analyze how their geometry and topology...
