Figure Legend:
A finite-element model for calculating the elastic energy of a film-substrate system at the delaminated buckled state (a). The calculated elastic (b) and potential (c) energy difference between the delaminated buckled and flat states as functions of the applied compressive strain and delaminated length. The calculated energy barrier for the transition from flat to delaminated buckled states (d). Optical microscopic images of the initiation and propagation of a delaminated buckle in a film-substrate system under compression (e). The delaminated buckle initiates at defects on the film-substrate interface as indicated by an arrow.
