Origami structures with morphing behaviours and unique mechanical properties are useful
in aerospace deployable structures, soft robots and mechanical metamaterials. Curved …

In this paper, we present a method for simulating the structural properties of curved-crease
origami through the use of a simplified numerical method called the bar and hinge model …

Origami-inspired metamaterials utilise geometric sheet transformations to generate and
control novel material mechanical properties. The majority of research effort has been …

With specific fold patterns, a 2D flat origami can be converted into a complex 3D structure
under an external driving force. Origami inspires the engineering design of many self …

Corrugations offer a convenient way to make thin, lightweight sheets into stiff structures.
However, traditional, v-shaped corrugations made from straight creases result in highly …

Conventional curved crease origami exhibits only Euclidean metrics at the crease, where
the surfaces on either side should consistently display convexity on one side and concavity …

A folded disk is bistable, as it can be popped through to an inverted state with elastic energy
localized in a small, highly-deformed region on the fold. Cutting out this singularity relaxes …

In this letter, we introduce a unique behavior seen in creased sheets where localized
changes in the folding (ie, a pinch) result in global bending and twisting deformations. Using …

A creased thin disk is generally bistable since the crease could be pushed through to form a
stable cone-like inverted state with an elastic singularity corresponding to the vertex of the …
