  • Nondestructive testing system and method using reflected shear horizontal guided waves
    Patent number: 12656317
    Abstract: A method and a system for nondestructive testing of a structure are provided. At least one ultrasonic probe is driven to cause at least one shear horizontal (SH) guided wave to propagate in the structure. At least one reflected guided wave signal is received from the structure to the at least one ultrasonic probe being driven. A comparison between an amplitude of the at least one reflected guided wave signal and an amplitude threshold is performed. A thickness of the structure is determined based on the comparison and a presence or an absence of at least one defect in the structure is detected based on the thickness as determined.
