Experimental Reserch on Buckling of Nano-Thin Film under Alternating Load
2011
Abstract In this paper, an experiment focus on thin film buckling under alternating load has been completed. The alternating-loading device based on piezoelectric ceramic which also integrates the force-displacement measure module, has been designed to offer the alternating loading to the metal films deposited on PMMA substrates. The initiation of the straight-side buckling and the cumulative buckling with propagation process are recorded and investigated by using a CCD camera and a optical microscope. It is found that buckling's initiation and propagation are influenced by the frequency, thickness of thin film and number of cycles.
