Wrinkling crystallography on spherical surfaces.
We present the results of an experimental investigation on the crystallography of the dimpled patterns obtained through wrinkling of a curved elastic system. Our macroscopic samples comprise a thin hemispherical shell bound to an equally curved compliant substrate. Under compression, a crystalline pattern of dimples self-organizes on the surface of the shell. Stresses are relaxed by both out-of...
متن کاملTunable phononic crystals via instability-induced interfacial wrinkling
We present a method to control wave propagation in highly deformable layered media by utilizing elastic insta-bility-induced wrinkling of interfacial layers. The onset of a wrinkling instability in initially straight interfacial layersoccurs when a critical compressive strain or stress is achieved [1]. Further compression beyond the critical strainleads to an increase in the wri...
متن کاملPHYSICAL MATHEMATICS SEMINAR Drag Control through Wrinkling on Curved Surfaces
We present the results of an experimental investigation on the wrinkling of positively curved surfaces and explore their use towards drag reduction applications. In our precision model experiments we make use of rapid prototyping techniques to cast samples with custom geometry and material properties out of silicone-based rubbers. Our structures consist of a thin stiff shell that is chemically ...
متن کاملHierarchical 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 کاملWrinkling Prediction with Adaptive Mesh Refinement
An adaptive mesh refinement procedure for wrinkling prediction analyses is presented. First the critical values are determined using Hutchinson’s bifurcation functional. A wrinkling risk factor is then defined and used to determined areas of potential wrinkling risk. Finally, a mesh refinement is operated.
