The stability of compressed thin films on substrates is discussed in the frame of the Föppl-Von Karman theory of thin plate buckling. The destabilization from pre-existing straight-sided to worm-like patterns is investigated and a critical stress is determined, above which the morphological change of the film occurs. Experimental investigations by atomic force microscopy have been also conducted and the different stages of this evolution have been characterized.
