Abstract:
A method of monitoring defects in a structure, the method comprising the steps of: (a) detecting the potential for a defect in the structure using a first detection method; (b) identifying the location on the structure of the defect using a second detection method; (c) determining if the defect exceeds an allowable limit, and, if so, transmitting information that the structure needs to be repaired; (d) if the defect does not exceed the allowable limit, then monitoring the structure by applying permanently installed ultrasonic sensor to the location; and (e) after step (d), repeatedly performing step (c) until the defect exceeds the allowable limit.
