摘要：

Kirigami, the Japanese art of paper cutting, can be used to generate complex 3D shapes from 2D sheets. Kirigami structures can also be highly stretchable and accommodate extremely large strains from common materials, such as aluminium, which allow relatively small strains at failure. The high stretchability of Kirigami makes it an ideal method for energy dissipation applications. This study investigates the mechanics and energy- dissipating behaviour of Kirigami made from metallic materials. A comprehensive analysis is conducted using a combination of reduced-order analytical modelling, finite element analysis, and experimental validation. The analytical model is used to produce a design methodology for energy-dissipating devices based on metallic ribbon Kirigami and is then applied as a case study to the design of a novel fall arrest system. The results of this study will enable the design of efficient, and highly customisable energy-dissipating systems based on metallic Kirigami.
