Harnessing Chaos for Shape Morphing of Bistable Systems
ORAL
Abstract
We investigate the shape morphing of a bistable system by harnessing chaotic dynamics. Our goal is to exploit chaotic behaviors such as switching, reverting, and vacillating oscillation to achieve efficient morphing of the bistable system. This study explores the effects of combining static bias forces with dynamic excitation, revealing non-fractal switching regions in the parameter space of a bistable system. Additionally, we examine the multistable behavior of a sequence of bistable discrete systems connected by flexible elements, demonstrating efficient pathways for achieving controlled shape transitions in adaptive applications.
