WebThe sleeves of Mona Lisa are wrinkled in the Yoshimura buckling pattern. In mechanical engineering, Yoshimura buckling is a triangular mesh buckling pattern found in thin-walled cylinders under compression along the axis of the cylinder, [1] [2] [3] producing a corrugated shape resembling the Schwarz lantern. The same pattern can be seen on 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].
