Tailoring Flexible Sheets Behavior: Origami and Kirigami in Fluid Flows

This lecture explores the manipulation of flexible surfaces in fluid environments through origami and kirigami techniques. By adding folds or cuts to sheets, researchers can control shape deformation and mechanical properties, impacting fluid-structure interactions. The discussion includes the use of symmetric cutting patterns to induce asymmetric deformations and extreme shape reconfiguration through origami folding to reduce fluid drag. The presentation combines experimental observations and theoretical insights to showcase the potential of engineered materials in enhancing performance in various applications.
