EXPERIMENTAL RESEARCH ON ULTRASONIC GUIDED WAVES DEFECT CLASSIFICATION BASED ON FRACTIONAL DIMENSION AND BP NEURAL NETWORK

EXPERIMENTAL RESEARCH ON ULTRASONIC GUIDED WAVES DEFECT CLASSIFICATION BASED ON FRACTIONAL DIMENSION AND BP NEURAL NETWORK

In recent years, ultrasonic guided waves technology has been widely used in nondestructive pipeline detection. However, the weak and insignificant defect echoes caused by the different types of tiny defects such as cracks, void, and dent deformation makes it difficult to identify and classify differ...
