Hierarchical wrinkling patterns †
This paper reports a simple and flexible method for generating hierarchical patterns from wrinkling instability. Complex features with gradually changing topographies are generated by using the spontaneous wrinkling of a rigid membrane (titanium) on a soft foundation (polystyrene) compressed via the diffusion of a solvent. We show that the morphology of these unreported wrinkled patterns is dir...
متن کاملGeometry and physics of wrinkling.
The wrinkling of thin elastic sheets occurs over a range of length scales, from the fine scale patterns in substrates on which cells crawl to the coarse wrinkles seen in clothes. Motivated by the wrinkling of a stretched elastic sheet, we deduce a general theory of wrinkling, valid far from the onset of the instability, using elementary geometry and the physics of bending and stretching. Our ma...
متن کاملWrinkling of Ultrathin Polymer Films
This paper presents a bilayer model to account for surface effects on the wrinkling of ultrathin polymer films. Assuming a surface layer of finite thickness, effects of surface properties on the critical strain, the equilibrium wavelength, and the wrinkle amplitude are discussed in comparison with conventional analysis. Experimental measurements of wrinkling in polymer films with thickness rang...
متن کاملAquagenic wrinkling of the palms.
A healthy 23-year-old woman presented with a six-month history of white lesions on her palms. The lesions would swell after being in water for 15 minutes and return to baseline 10–15 minutes after drying. The patient did not take medications except for oral contraceptive pills, and she was not aware of a family history of similar complaints. Physical examination showed white, slightly transluce...
متن کاملWrinkling of a bilayer membrane.
The buckling of elastic bodies is a common phenomenon in the mechanics of solids. Wrinkling of membranes can often be interpreted as buckling under constraints that prohibit large-amplitude deformation. We present a combination of analytic calculations, experiments, and simulations to understand wrinkling patterns generated in a bilayer membrane. The model membrane is composed of a flexible sph...
