Draping films: a wrinkle to fold transition.
A polymer film draping over a point of contact will wrinkle due to the strain imposed by the underlying substrate. The wrinkle wavelength is dictated by a balance of material properties and geometry; most directly the thickness of the draping film. At a critical strain, the stress in the film will localize, causing hundreds of wrinkles to collapse into several discrete folds. In this Letter, we...

Submitted for the MAR10 Meeting of The American Physical Society Draping Films: A Wrinkle to Fold Transition DOUGLAS HOLMES, Princeton University, ALFRED J. CROSBY, Universtity of Massachusetts Amherst — This work focuses on the wrinkle-to-fold transition in glassy and elastomeric thin films. In biological systems, the process of folding is critical to morphogenesis, defining such features as t...
متن کاملWrinkle motifs in thin films
On length scales from nanometres to metres, partial adhesion of thin films with substrates generates a fascinating variety of patterns, such as 'telephone cord' buckles, wrinkles, and labyrinth domains. Although these patterns are part of everyday experience and are important in industry, they are not completely understood. Here, we report simulation studies of a previously-overlooked phenomeno...
متن کاملWrinkle Patterns of Anisotropic Crystal Films on Viscoelastic Substrates
This paper presents a nonlinear mathematical model for evolution of wrinkle patterns of an anisotropic crystal film on a viscoelastic substrate layer. The underlying mechanism of wrinkling has been generally understood as a stress-driven instability. Previously, theoretical studies on wrinkling have assumed isotropic elastic properties for the film. Motivated by recent experimental observations...
متن کاملDynamics of wrinkle growth and coarsening in stressed thin films.
A stressed thin film on a soft substrate can develop complex wrinkle patterns. The onset of wrinkling and initial growth is well described by a linear perturbation analysis, and the equilibrium wrinkles can be analyzed using an energy approach. In between, the wrinkle pattern undergoes a coarsening process with a peculiar dynamics. By using a proper scaling and two-dimensional numerical simulat...
