Our research focuses on elucidating the mechanics underlying origami and kirigami systems, with a specific emphasis on their applications in enhancing urban ventilation and structural and construction efficiency. By employing a multidisciplinary approach integrating computational simulations, experimental analyses, and theoretical modeling, we aim to unravel the fundamental principles governing the behavior of these folded and cut structures.

Our investigations delve into the aerodynamic properties of origami-inspired louvers and lattice-cut kirigami configurations, probing their efficacy in promoting natural ventilation within urban environments. Additionally, we explore the engineering potential of curved-crease origami bases, investigating the influence of crease curvature on mechanical tunability and bistability. Furthermore, our research endeavors extend to the development of kirigami-based structural systems tailored for efficient assembly, cost-effectiveness, and load-bearing applications. By examining the interplay between polygonal shapes, cut patterns, and mechanical behavior under tension and compression loads, we aim to understand the underlying principles governing the structural integrity and performance of rotational kirigami units. Through the synthesis of experimental validation and computational modeling, we seek to establish robust design guidelines for scalable kirigami structures capable of withstanding diverse loading conditions.
