论文摘要

基里加米(Kirigami)涉及切割平坦的薄板,使其可以通过内部瓷砖的协调旋转从封闭的紧凑型配置变为开放部署的结构。通过识别和概括使这种艺术形式的几何约束,我们为紧凑的可重构基里加米模式提出了一个设计框架,该框架可以从封闭和紧凑的配置转变为符合任何规定的目标形状的部署状态,并随后将其收缩为不同的封闭和紧凑型配置。我们进一步建立了生产基里加米模式的条件,这些模式是可重新配置且可部署的,使我们能够通过部署州的零能量家族连接紧凑型状态。总的来说,我们的逆设计框架为创建形状变形材料结构的新途径提供了新的道路。

Kirigami involves cutting a flat, thin sheet that allows it to morph from a closed, compact configuration into an open deployed structure via coordinated rotations of the internal tiles. By recognizing and generalizing the geometric constraints that enable this art form, we propose a design framework for compact reconfigurable kirigami patterns, which can morph from a closed and compact configuration into a deployed state conforming to any prescribed target shape, and subsequently be contracted into a different closed and compact configuration. We further establish a condition for producing kirigami patterns which are reconfigurable and rigid deployable allowing us to connect the compact states via a zero-energy family of deployed states. All together, our inverse design framework lays out a new path for the creation of shape-morphing material structures.
