摘要：
In this paper, the vibration characteristics of bonded structures were experimentally investigated by incorporating amplitude fluctuation electronic speckle pattern interferometry (AF-ESPI) with modal testing technique. A special casting procedure was employed to manufacture the naturally bonded structures to avoid the influence resulted from the adhesive Vibration characteristics of bonded structures with different geometrical combinations of constituent adherends and the influence of presence of an interfacial crack were investigated.
