High Aspect Ratio Wrinkles via Substrate Prestretch

Authors


Abstract

image

A non-fractured, high aspect ratio wrinkled surface is successfully fabricated. Building upon recently developed models of the localization transition and the current knowledge of surface failures, the wrinkling mode is stabilized at high strain, doubling the accessible wrinkling aspect ratio to the currently reported value. This high aspect ratio surface provides significant promise for future wrinkle-based applications.
