Whereas wrinkles tend to be uniformly distributed, ridges are localized. The wrinkle-to-ridge transition is unstable (subcritical), resulting in large amplitude changes. The nature and morphology of the ridges is studied and quantified by experiments and numerical simulations.en-USThin film bucklingwrinklingridge localizationsubstrate pre-stretchridge networksJournal Article2015-02-02Takei, A., Jin, L., Hutchinson, J.W2015-02-2410.1002/adma.201306162
