Abstract
The art form of kirigami has recently attracted interest from engineers and scientists for generating complex three-dimensional structures from flat sheet-like materials. When thin metal sheets are used, the deformation can become plastic and localized, allowing for permanent intricate shapes to be formed. In this study, the illustrative case of an annular plate under diametral tension is considered, and it is shown that the deformed shape can be considered as a spatial mechanism of localized plastic yield lines connected to largely undeformed regions. This technique provides useful information for the design of novel permanently deployable structures.
