Such facet-binding will induce \u003ci\u003eself-locking\u003c/i\u003e so that the overall structure stays at a pre-specified configuration without additional locking elements or actuators. Self-locking offers many promising properties, such as programmable deformation ranges and piecewise stiffness jumps, that could significantly advance many adaptive structural systems. However, despite its excellent potential, the origami self-locking features have not been well studied, understood, and used. To advance the state of the art, this research conducts a comprehensive investigation on the principles of achieving and harnessing self-locking in 4-vertex origami structures. Especially, for the first time, this study expands the 4-vertex structure construction from single-component to dual-component designs and investigates their self-locking behaviours. By exploiting various tessellation designs, this research discovers that the dual-component designs offer the origami structures with extraordinary attributes that the single-component structures do not have, which include the existence of flat-folded locking planes, programmable locking points and deformability. Finally, proof-of-concept experiments investigate how self-locking can effectively induce piecewise stiffness jumps. The results of this research provide new scientific knowledge and a systematic framework for the design, analysis and utilization of self-locking origami structures for many potential engineering applications.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
