Experimental Research on Buckling of Nano-thin Film under Impact Load

摘要

The experiments focused on thin film buckling under impact load had been completed. The axial impact experiments were done to different films on the PMMA substrate with the drop hammer device, the buckling images of the film surface were recorded after impact, and the problem of stress release was studied. It was found that buckle's initiation and propagation were influenced by the materials of thin films and the impact times, and meanwhile buckle's local distribution phenomenon was also found.
