“…Bar and hinge models use bar elements to capture stretching and shearing of panels and use rotational spring elements to capture crease folding 57,58 . Unlike existing bar and hinge models for thick origami 59,60 , the thick-panel-connector formulation simulates thick Article https://doi.org/10.1038/s41467-024-46667-0 origami panels and connectors separately, so that we can appropriately represents their different stiffnesses. Thus, this formulation can simulate the load-carrying behaviour of MUTOIS appropriately as demonstrated in Fig.…”

Existing Civil Engineering structures have limited capability to adapt their configurations for new functions, non-stationary environments, or future reuse. Although origami principles provide capabilities of dense packaging and reconfiguration, existing origami systems have not achieved deployable metre-scale structures that can support large loads. Here, we established modular and uniformly thick origami-inspired structures that can deploy into metre-scale structures, adapt into different shapes, and carry remarkably large loads. This work first derives general conditions for degree-N origami vertices to be flat foldable, developable, and uniformly thick, and uses these conditions to create the proposed origami-inspired structures. We then show that these origami-inspired structures can utilize high modularity for rapid repair and adaptability of shapes and functions; can harness multi-path folding motions to reconfigure between storage and structural states; and can exploit uniform thickness to carry large loads. We believe concepts of modular and uniformly thick origami-inspired structures will challenge traditional practice in Civil Engineering by enabling large-scale, adaptable, deployable, and load-carrying structures, and offer broader applications in aerospace systems, space habitats, robotics, and more.

Hybrid joints consist of living trees and industrial materials are the solutions to realize the living architectures. However, the mechanism of grow‐contact‐swallow behavior remains ambiguous. Some computational graphical methods have struggled to generate the tree geometry. However, physical features such as stiffness were not considered. In this paper, we proposed a grow‐contact simulation method for describing the swallowing process to generate hybrid joints. Our temporal evolution approach is implemented using the Non‐Uniform Rational B‐Spline curves, and the genetic algorithms. We formulate the grow‐contact process as a solution for optimization problem that leads to the state with minimal total generalized potential energy. We conclude that the simulation results explain 4 general contact behaviors, concerning stiffness, and the age of the tree as the mechanical metrics. Especially for swallowing behavior, the three‐dimensional geometry prediction shows potential for the design of hybrid joints for living architectures.
