Energy Bounds for a Compressed Elastic Film on a Substrate
We study pattern formation in a compressed elastic film which delaminates from a substrate. Our key tool is the determination of rigorous upper and lower bounds on the minimum value of a suitable energy functional. The energy consists of two parts, describing the two main physical effects. The first part represents the elastic energy of the film, which is approximated using the von Kármán plate...
متن کاملUndulation instability of a compressed elastic film on a nonlinear creeping substrate
Undulation instabilities in a tri-layer system subject to variations of temperature are studied for the purpose of revealing a mechanism leading to the failure of thermal barrier systems. A pre-compressed oxide film with a small initial non-planarity is attached to a metal bond coat layer that is, in turn, attached to a thick superalloy substrate. The oxide film and the superalloy substrate are...
متن کاملWrinkling of a compressed elastic film on a viscous layer
A compressively strained elastic film bonded to a viscous layer can form wrinkles. The present study provides a theoretical model for the wrinkling process. The elastic film is modeled with the nonlinear theory of a thin plate subject to in-plane and out-of-plane loads. The flow of the viscous layer is modeled with the theory of lubrication. The interface between the elastic film and the viscou...
متن کاملInstability of a compressed elastic film on a viscous layer
A flat, compressed elastic film on a viscous layer is unstable. The film can form wrinkles to reduce the elastic energy. A linear perturbation analysis is performed to determine the critical wave number and the growth rate of the unstable modes. While the viscous layer has no effect on the critical wave number, its viscosity and thickness set the time scale for the growth of the perturbations. ...
متن کاملKinetic wrinkling of an elastic film on a viscoelastic substrate
A compressed elastic film on a compliant substrate can form wrinkles. On an elastic substrate, equilibrium and energetics set the critical condition and select the wrinkle wavelength and amplitude. On a viscous substrate, wrinkle grows over time and the kinetics selects the fastest growing wavelength. More generally, on a viscoelastic substrate, both energetics and kinetics play important roles...
