Webtion) to study the buckling behavior of such systems. The buckling profile of the ribbon is assumed to be a sinusoidal form w = 1 2 A(1−cos2πx/L 1), which satis-fies vanishing displacement and slope at the two ends x = 0 and x = L 1. The amplitude A is determined by the energy method. The above model is referred as small deformation model ... WebAn analytical solution is obtained for the buckling geometr (wavelength and amplitude) and the maximum strain in buckled thin film. This solution agrees very well with the experiments, and shows explicitly how buckling can significantly reduce the thin film strain to achieve the system stretchability.",
