ABSTRACT:
A system and method for identifying defects in a repair patch applied to a structure are provided. The system includes a sheet of material configured to be attached to the structure, and a mechanism operable to generate stress waves within and along the sheet of material. The system also includes a plurality of non-destructive sensors carried by the sheet of material. Each sensor is capable of detecting the stress waves. The system further includes a data acquisition system capable of communicating with the sensors such that the data acquisition system is also capable of generating information indicative of at least a portion of the sheet of material based on the data detected by the sensors.
