Augustine Professor of Engineering from Princeton University. With his talk "Origami," Paulino delved into the mesmerizing realm of geometric mechanics, unraveling the impact of geometry on behavior and properties, particularly within origami assemblages. The Tedori-Callinan Lecture Series, made possible by the generosity of Letty Tedori-Callinan and her husband Jim, honors Letty's late father, Fred Tedori Sr., an advocate of education who instilled in his daughters the importance of pursuing careers in engineering. Letty herself, an alumna of the Mechanical Engineering and Applied Mechanics department, epitomized excellence during her undergraduate studies, showcasing qualities of curiosity, creativity, diligence, responsibility, and attention to detail. Building upon this legacy of innovation, Glaucio Paulino's lecture offered insights into the structural complexities of origami. A highlight of the presentation was the introduction of a groundbreaking reduced-order-model, featuring an enhanced bar-and-hinge framework, designed to simulate the behavior of origami assemblages with unprecedented accuracy. Through this model, Paulino and his team unravel the intricacies of tubular origami and kirigami structures, particularly focusing on the stiffness characteristics derived from the renowned Miura-ori folding pattern. The culmination of Paulino's research journey leads to the development, fabrication, and testing of micron-scale metamaterials using direct laser writing technology. These metamaterials exhibit remarkable mechanical properties, including anisotropy, reversible auxeticity, and remarkable shape recoverability, making them a beacon of innovation in the field of origami engineering.
