Curved creases redistribute global bending stiffness in corrugations: theory and experimentation

SR Woodruff, ET Filipov - Meccanica, 2021 - Springer
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 …

Cutting holes in bistable folds

T Yu, I Andrade-Silva, MA Dias, JA Hanna - Mechanics Research …, 2022 - Elsevier
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 …

Bending and twisting with a pinch: Shape morphing of creased sheets

SR Woodruff, ET Filipov - Extreme Mechanics Letters, 2022 - Elsevier
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 …

Bistability and equilibria of creased annular sheets and strips

T Yu - International Journal of Solids and Structures, 2022 - Elsevier
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 …

How Curved Creases Enhance the Stiffness and Enable Shape Morphing of Thin-Sheet Structures

S Woodruff - 2022 - deepblue.lib.umich.edu
When a thin sheet is folded about curved creases, the resulting shape resists loads in some
directions and deforms into compact states in other directions. These curved-crease, origami …
