This award supports fundamental research to establish a design methodology for composite structures by taking advantage of Kirigami cutting principles and snap-through multi-stability. Composite structures combine multiple materials to achieve desirable properties and are vital for many engineering systems. Snap-through multi-stable structures can quickly transition from one stable state to another. They can bear weight and perform other functions such as shape morphing, vibration control, and energy harvesting. However, the current-state-of-art in multi-stable composites is limited in terms of the achievable shapes and functionalities. This research uses Kirigami cutting principles to fundamentally expand the performance space of multi-stable composites. The design methodology synergizes with advanced layer-by-layer manufacturing technology, enabling a two-dimensional build to transform into a complex three-dimensional structure through the optimal design of fiber ply properties and Kirigami-inspired cutting patterns. This will lead to novel structural designs that offer sophisticated functionalities, such as shape reconfiguration and on-demand mechanical property programming. These structures can benefit a number of industries, including aerospace, automotive, and robotics, by enhancing system performance and sustainability. This award will also support efforts to enhance educational activities at Clemson University and nearby communities in South Carolina. Research results will be used in existing outreach networks like Clemson EMAG!NE to inspire the public via combining engineering and the art of Kirigami paper cutting.This research will, for the first time, systematically incorporate the Kirigami cutting principle in an engineering-relevant optimal design framework. It is expected to create significant leaps in adaptive composites, Kirigami applications, and multi-level, multi-objective design optimization. The research goals will be achieved by 1) deriving mathematical linkages between design variables and performance outputs via a new reduced-order mechanics model using F?ppl-von K?rm?n (FvK) shell theory and customized shape functions; 2) developing practical design guidelines and constraints via extensive experimental testing; and 3) deriving multi-disciplinary synthesis method based on bi-level optimization. Results of the three tasks will be integrated into the design framework. Throughout the course of this project, the research team will address many technical challenges with broad relevance, including the complex non-free boundaries between composite patches, fabrication uncertainties, and robustness in multi-level design optimization.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持基础研究，以利用 Kirigami 切割原理和快速多重稳定性建立复合材料结构的设计方法。 复合结构结合多种材料以获得所需的性能，对于许多工程系统至关重要。突弹式多稳态结构可以快速从一种稳定状态转变到另一种稳定状态。它们可以承受重量并执行其他功能，例如形状变形、振动控制和能量收集。 然而，目前多稳定复合材料的最新技术在可实现的形状和功能方面受到限制。 这项研究利用 Kirigami 切割原理从根本上扩展了多稳态复合材料的性能空间。该设计方法与先进的逐层制造技术相结合，通过纤维层特性的优化设计和受剪纸启发的切割图案，使二维结构转变为复杂的三维结构。这将带来新颖的结构设计，提供复杂的功能，例如形状重新配置和按需机械性能编程。这些结构可以通过增强系统性能和可持续性来使许多行业受益，包括航空航天、汽车和机器人技术。 该奖项还将支持克莱姆森大学和南卡罗来纳州附近社区加强教育活动的努力。研究成果将用于克莱姆森 EMAG!NE 等现有的推广网络，通过将工程与剪纸艺术相结合来启发公众。这项研究将首次系统地将剪纸切割原理纳入与工程相关的最佳方案中。设计框架。 预计它将在自适应复合材料、Kirigami 应用和多层次、多目标设计优化方面实现重大飞跃。 研究目标将通过以下方式实现：1) 使用 F?ppl-von K?rm?n (FvK) 壳理论和定制形状函数，通过新的降阶力学模型导出设计变量和性能输出之间的数学联系； 2）通过广泛的实验测试制定实用的设计指南和约束； 3)推导了基于双层优化的多学科综合方法。 这三项任务的结果将被整合到设计框架中。 在整个项目过程中，研究团队将解决许多具有广泛相关性的技术挑战，包括复合材料贴片之间复杂的非自由边界、制造不确定性以及多级设计优化的鲁棒性。该奖项反映了 NSF 的法定使命，并具有通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
