 Abstract:

Wrinkling vs. long-wavelength instability envelope for multi-layered soft composite: Predictive analytical and finite element models are presented to reveal the instability mechanics governing reversible wrinkling of interfacial layers. The biomimetic guidelines for the design of reversible, tunable, and multi-functional layered soft composites with transforming interfacial layers are developed and verified via 3D printed prototypes.
