The present disclosure provides a system and method for real-time visualization of a material during ultrasonic non-destructive testing. The system includes a graphical user interface (GUI) capable of showing a three-dimensional (3-D) image of a composite laminate constructed of a series of two-dimensional (2-D) cross sections. The GUI is capable of displaying the 3-D image as each additional 2-D cross section is scanned by an ultrasonic testing apparatus in real time or near real time, including probable defect regions that contain a flaw such as a hole, crack, wrinkle, or foreign object within the composite. Furthermore, in one embodiment, the system includes an artificial intelligence capable of highlighting defect areas within the 3-D image in real time or near real time and providing data regarding each defect area, such as the depth, size, and/or type of each defect.

Disclosed herein is a system and method for inspecting a bonded structure in a component. The system includes an integrated probe and a processor coupled to the integrated probe. The integrated probe includes an ultrasonic component and a laser component. The ultrasonic component is configured to transmit pulsed sound waves into the bonded structure and receive reflected pulsed sound waves from the bonded structure. The laser component is configured to generate laser pulses and direct the laser pulses to the bonded structure to generate tension waves across the bonded structure. The processor is configured to test a bonded structure in the component. Further, the processor includes a pre-test module configured to operate the ultrasonic component in a pre-test mode, a test module configured to operate the laser component in a test mode, and a post-test module configured to operate the ultrasonic component in a post-test mode.

A characterization device for non-destructively characterizing a material includes emitter/receiver cells, each cell being able, in an emit mode, to emit ultrasound waves towards the material for characterizing, and, in a receive mode, to receive ultrasound waves that have been transmitted through the material. The non-destructive characterization device includes a ring made up of a plurality of adjacent angular sectors, each angular sector including ultrasound cells stacked in a radial direction of the ring.

There is provided detection instrumentation for the detection of transverse rail defects in rail head hitherto considered untestable on account of acoustic signal attenuation problems of horizontal lamination defects. The detection instrumentation comprises a pulse-echo acoustic transducer having a wear face for contacting a fillet of the rail and being aimed towards a head of the rail such that the transmitter transmits acoustic signals into the head and the receiver receives acoustic signals reflected at differing depths within the head. A signal receiver operably coupled to the receiver times the acoustic signals according to a timeseries railhead depth position scale. Analysis of the depth positions of the reflected acoustic signals according to relative positioning of the instrumentation along the rail may identify the transverse rail defects.

A method for nondestructive multispectral vibrothermography inspection of a component, includes generating ultrasonic excitations in a component over a broad range of frequencies; determining a spectral signature in the component from the excitations; comparing the spectral energy signature against database 270 of correlations between vibrational frequencies of a multiple of components and the spectral energy distribution thereof, and classifying the component based on the database data.

A reflection-diffraction-deformation flaw detection method employs a transverse wave oblique probe. When an ultrasonic transverse wave encounters a defect during propagation, a reflected wave, a diffracted wave, and a deformed wave are generated. Through a comprehensive analysis of these waves, the presence or absence of the defect is determined by the reflected wave having reflection characteristics and the diffracted wave having the diffraction characteristics. The shape and size of the defect are determined by the deformed wave having deformation characteristics, namely the deformed surface wave generated at the endpoints of the defect which propagates on the defect surface. Furthermore, by the combination of paths trailed by the deformed surface wave, the deformed transverse wave, and the deformed longitudinal wave that are generated by the defect as well as that trailed by the transmit transverse wave, causes of all those waves in the screen can be revealed.
