Application of Simple Notch to Selective Separation of Adherend Bonded With Resin Adhesive by Pulsed Discharge in Air

This study reports the application of a simple conical notch punched on a bonded structure set in air for the selective separation of an adherend by pulsed discharge, with the discharge passage inside the adhesive bonding adherend. A simulation of the electrical field indicated that the field around the notch tip was highest compared with that at the edge where the field concentrated in the normal...
