Abstract: Zipper-coupled tubes are a unique structure consisting of two tubes with zig-zag walls that, when coupled in a zipper fashion, resist compression in the normal direction. A wider application of zipper-coupled tubes, however, ...

Abstract: We demonstrate analytically that it is possible to construct a developable mechanism on a cone that has rigid motion. We solve for the paths of rigid motion and analyze the properties of this motion. In particular, we ...

Abstract: Of the many valid configurations that a curved fold may assume, it is of particular interest to identify natural—or lowest energy—configurations that physical models will preferentially assume. We present normalized ...
