Abstract

Kirigami is the ancient Japanese art of cutting and folding paper, while auxetics is referred to a class of structures and materials exhibiting a negative Poisson's ratio effect. In this workshop we will give examples on how auxetic configurations can be used for shape morphing and Deployment and and how Kirigami (and paper cutting) design principles can be used to produce auxetics and other producers with abnormal deformation mechanisms with any material substrate for composites manufacturing. We will describe in particular morphing wingbox, deployable reflectors in shape memory alloy, Classes Of Kirigami-inspired Cores and morphing structures for wide ranges of applications - from high-performance sandwich panels to arms for soft robotics. We will also describe concepts of mechanical metamaterials with auxetic characteristics for energy absorption, biomedical and vibration damping applications.
