When a piezoelectric film is glued on the surface of a structure member subjected to mechanical load, a distribution of electric potential is induced. In the existence of defects in the member, a characteristic variation of electri c potential is observed. Based on this phenomenon, the passive electric potential CT method is developed for detection and identification of defects in a structure. In this study, the applicability of the passive electric potential CT method to the detection and identification o...
