Abstract: Systems and methods for training a machine learning model for non-destructive evaluation. A plurality of training samples are generated, with a subset of the plurality of training samples representing an article with a defect or a combination of defects. Training samples are generated by generating a virtual model of the article with defect at a computer system, generating a simulated signal representing an output of a non-destructive evaluation system scanning the physical article using the virtual model at the computer system, and associating a representation of the simulated signal with parameters representing a characteristic of the virtual model of the article with defects. The machine learning model is trained on the plurality of training samples. The trained machine learning model is applied on to measurements collected from physical articles to characterize or quantify defects.

Abstract: A system and method for sizing defects in solid structures using guided waves. The system includes a magnetostrictive-strip EMAT transducer comprising at least one biasing static magnetic field, at least one RF coil for fixed-wavelength measurements, at least one RF coil for variable-wavelength measurements, and a strip of highly magnetostrictive material that is coupled with the structure. The fixed-wavelength RF coil permits obtaining measurements of amplitude and frequency content of signals reflected and/or attenuated when traveling through the structure which are used to estimate the size and geometry of any defects in this structure. The variable-wavelength RF coil permits recording the frequencies that are cut off or pass through the structure to also estimate the size of any defects in the structure. The fixed-wavelength sizing and geometry assessment is used to determine whether the variable-wavelength estimate is valid. The final assessment is based on the fixed-wavelength estimate, the variable-wavelength estimate, or a combination of both.

Abstract: A device for estimating a mechanical property of a sample is disclosed herein. The device may include a chamber configured to hold the sample; a transmitter configured to transmit a plurality of waveforms, including at least one forcing waveform; and a transducer assembly operatively connected to the transmitter and configured to transform the transmit waveforms into ultrasound waveforms. The transducer assembly can also transmit and receive ultrasound waveforms into and out of the chamber, as well as transform at least two received ultrasound waveforms into received electrical waveforms. The device also includes a data processor that can receive the received electrical waveforms; estimate a difference in the received electrical waveforms that results at least partially from movement of the sample; and estimate a mechanical property of the sample by comparing at least one feature of the estimated difference to at least one predicted feature, wherein the at least one predicted feature is based on a model of an effect of the chamber wall. Finally, the device can also include a controller configured to control the timing of the ultrasound transmitter and data processor.

The tool generates a model representing the aquatic medium as a three-dimensional (3D) Gaussian random field, the 3D Gaussian random field being described by one or more correlation functions. The tool determines a propagation trajectory of a sound wave in the aquatic medium based on the 3D Gaussian random field.

Abstract: 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.

Abstract: A method for monitoring a service state of a switch rail based on feature fusion includes: mounting an ultrasonic guided wave monitoring apparatus on the switch rail to perform online defect identification and simulation of the switch rail, and establishing a baseline signal library, where the ultrasonic guided wave monitoring apparatus generates a guided wave signal propagating along the switch rail and receives an echo signal of the guided wave signal; performing feature extraction; extracting a healthy feature vector, and nondimensionalizing; selecting a defect-sensitive feature, and acquiring, by a BPSO algorithm, a best feature subset; training an LS-SVM through the best feature subset by a cross-validation method to acquire an automatic online defect identification model of the switch rail based on the LS-SVM; and monitoring the switch rail by the automatic online defect identification model of the switch rail based on the LS-SVM.

Abstract: Methods and systems for solving inverse problems arising in systems described by a physics-based forward propagation model use a Bayesian approach to model the uncertainty in the realization of model parameters. A Generative Adversarial Network (“GAN”) architecture along with heuristics and statistical learning is used. This results in a more reliable point estimate of the desired model parameters. In some embodiments, the disclosed methodology may be applied to automatic inversion of physics-based modeling of pipelines.
