Webbuckling patterns.9,10 Eﬀorts to rationalize the buckling of such bilayer systems date as far back as the seminal work of Allen11 in the 1960’s, originally with the intent of studying skin buckling and failure of sandwich structures. More recently, the onset of surface buckling patterns has been studied in the Websinusoidal buckling pattern has been shown to localize into a well-deﬁned fold, see [22] for a review. This manifestation of a localized buckling pattern has been explained in the case of an inﬁnitely long beam (L → ∞) [23] where the shape of the beam is associated to an homoclinic orbit in the corresponding phase space [24]. sibley hospital mri scheduling
