Abstract
The effects of electrical treatment on the residual strength of joints bonded with an electricallydisbonding adhesive have been investigated experimentally.The adhesive can be separated by applying electric current.The ARCAN experimental setup was used to measure the residual strength of the joints subjected to multiaxial combined loads after applying current. The results show that thedecrease ratio of the residual strengths dose not depend on the direction of radial loading when the current-carrying conditions are kept the same. It depends on the areal density of total charge passing through the interface rather than applied voltage. The two results give a prediction method of the residual strength based on the initial strength under combined stress conditions and the areal densityof total passing charge. In Order to verify the prediction method, experiments of a simple separationmodel having spring mechanism were carried out.The model could be separated by applying currentand the separation could be predicted by this method very well.
