Defects Detection and Recognition in Aviation Riveted Joints by Using Ultrasonic Echo Signals of Non-Destructive Testing

Oleg S. Amosov et al.

Summary: The study addresses the problem of defects detection and recognition in aviation riveted joints by proposing a solution using a deep neural network with a recurrent LSTM layer. An example of defect detection and recognition in rivets is considered, achieving high accuracy in simulation with ultrasonic flaw detector echo signals. Fractal properties of non-destructive testing echo signals are shown to be useful in defect detection.
