Adhesion-Induced Instability Patterns in Thin Confined Elastic Film

  title={Adhesion-Induced Instability Patterns in Thin Confined Elastic Film},
  author={Animangsu Ghatak and Manoj K Chaudhury},
Adhesion-induced instability has been observed at the interface of a flexible plate and a thin elastic film bonded to a rigid substrate. The surface of the confined film develops undulations almost instantaneously, and instability patterns appear in the form of fingers or bubbles at the interface. The characteristic wavelengths of these instabilities remain independent of all material and geometrical properties of the system except the thickness of the film. These observations contrast sharply… CONTINUE READING
