Abstract

The applicability of the active pulse echo method to defect identification was investigated. In this method, ultrasonic waves are activated by applying an electric pulse to the piezo film and waves reflected at crack tip are received on the piezoelectric film. In this paper the influence of the number of probes is investigated. The method was applied to experimental data also. It was found that an accurate identification can be made using 6 or more probes.
