Shape-morphing structures have the ability to transform from one state to another, making them highly valuable in engineering applications. This study proposes a two-stage shape-morphing framework, inspired by kirigami structures, to design structures that can deploy from a compacted state to a prescribed state under certain mechanical stimuli — although the framework can also be extended to accommodate various physical fields, such as magnetic, thermal and electric fields. The framework establishes a connection between the geometry and mechanics of kirigami structures. The proposed approach combines finite element analysis (FEA), genetic algorithm (GA), and an analytical energy-based model to obtain kirigami designs with robustness and efficiency. We expect that this approach to the design of kirigami structures will open up new avenues of research and application in shape-morphing structure design.

可编程形状变形 kirigami 结构的逆向设计


形状变形结构具有从一种状态转换为另一种状态的能力，这使得它们在工程应用中非常有价值。这项研究提出了一个两阶段的形状变形框架，其灵感来自折纸结构，以设计可以在某些机械刺激下从压缩状态部署到规定状态的结构——尽管该框架也可以扩展以适应各种物理场，例如磁场、热场和电场。该框架在剪纸结构的几何形状和力学之间建立了联系。所提出的方法结合了有限元分析 （FEA）、遗传算法 （GA） 和基于能量的分析模型，以获得具有稳健性和效率的折纸设计。我们预计这种折纸结构设计的方法将为形状变形结构设计的研究和应用开辟新的途径。
