摘要： The present disclosure provides methods and systems for performing ultrasonic testing. Reflected acoustic waves are obtained at a detector, the reflected acoustic waves produced by at least one insonification of a component to be tested. The reflected acoustic waves are processed to produce a representation of the component. A location of the component to be tested within the representation of the component is determined. A portion of the representation associated with the component is analyzed to detect a presence of a defect in the component to be tested. An alert indicative of the defect in the component is issued responsive to detecting the presence of the defect.

摘要： 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.

摘要： There is described a probe for non-destructive testing of a curved object, the probe comprising an arrangement of magnets and coils configured for generating shear horizontal guided waves for propagating longitudinally in the object, the probe having a top surface, a bottom surface, and two opposed ends extending between the top surface and the bottom surface, the bottom surface having a non-zero curvature between the two opposed ends and matable with an outer surface of the curved object.
