Fringe Instability in Constrained Soft Elastic Layers

Soft elastic layers with top and bottom surfaces adhered to rigid bodies are abundant in biological organisms and engineering applications. As the rigid bodies are pulled apart, the stressed layer can exhibit various modes of mechanical instabilities. In cases where the layer’s thickness is much smaller than its length and width, the dominant modes that have been studied are the cavitation, interfacial and fingering instabilities.

Nonlinear geometric effects in mechanical bistable morphing structures


Bistable structures, exemplified
by the Venus flytrap and slap bracelets, can switch between different
functional shapes upon actuation, and have important applications in
mechanical/electro-mechanical devices ranging from bio-inspired robots to
deployable aeroplane wings. Despite numerous efforts in modeling such large
deformation of shell structures, the roles of mechanical and nonlinear geometric
effects on bistability remains elusive. Closely related, emerging challenges
include modeling the spontaneous curving and buckling of thin objects such as
