Structural function from sequential, interacting elastic instabilities
April 2023 • Ed Wheatcroft, Jiajia Shen, Rainer Groh, Alberto Pirrera, Mark Schenk
Elastic instabilities have traditionally been considered a failure mechanism; however, recent years have seen numerous studies exploiting instabilities as a means to achieve structural functionality. By contrast, interacting instabilities and compound buckling are still largely viewed as a failure mechanism. In this paper, we show that interacting instabilities can also be exploited to achieve bespoke functionality. We focus on ‘sequential instabilities’, whose associated critical points cannot both lie on a funda…
