SEMINAR: Harnessing Mechanical Instabilities for Functionalities
October 2, 2020 @ 10:00 am - 11:00 am
Mechanical instabilities have historically been viewed as a failure mechanism in materials and engineering structures. Over the past decade, the incredible advantages of controllable surface and structural instabilities have been harnessed in soft materials at all scales for functionalities, including stretchable electronics, surface-related multifunctionality, and soft robotics. In this talk, I will discuss our recent work on leveraging mechanical instability in soft materials and structures for achieving extreme properties and high performances. First, I will discuss mechanics of surface instabilities including hierarchical wrinkling and extreme buckling-driven delamination in film-substrate systems, as well as their potential applications in multifunctional smart window and stretchable electronics. Next, I will talk about our recent work on harnessing structural instability for energy saving building envelope and shape shifting.
Dr. Jie Yin joined the Mechanical and Aerospace Engineering Department at NC State University as an Assistant Professor in 2019 Fall. Dr. Yin received his Ph.D. from Columbia University. Dr. Yin is the recipient of the NSF Career Award and Extreme Mechanics Letter (EML) Young Investigator Award. His group’s current research focuses on mechanics and functionality of soft materials, mechanical metamaterials, and mechanics guided design of soft robotics.
