Abstract

The generation and expanding process of the film buckling under different loads were observed by the OLYMPUS microscope, and the surface buckling morphology under different loads also were observed in the same time. The same kind of specimen was also used to study buckling under a number of load-unload circles, and the result shows that at this process, the film looked like "fatigue", Only smaller load, we can observe a lot of surface buckling on the film. Drop hammer device and the swing hammer device were developed in order to study the process of buckling of film under dynamic load, in the end we have the preliminary understanding of film-substrate which is in the high strain rate.
