This paper presents a comprehensive review of the current state of knowledge of second
harmonic generation (SHG) measurements, a subset of nonlinear ultrasonic nondestructive …

Mechanical properties of materials tend to deteriorate over time and thus become
responsible for cracks and malfunctions in mechanical components or civil structures. Non …

The assessment of creep damage in steels employed in the power generation industry is
usually carried out by means of replica metallography, but the several shortcomings of this …

This research uses nonlinear Rayleigh waves to characterize the damage due to plastic
deformation in A36 steel specimens subjected to quasi-static, monotonic tension, and low …

Herein, we developed a nonlinear ultrasonic three-wave mixing technique to more
accurately detect and localize early-stage fatigue cracks. First, we derived the theoretical …

The traditional nonlinear ultrasonic technique, as typified by the second-harmonic
generation and the frequency mixing response, can be employed to identify and …

This research presents a new technique for nonlinear Rayleigh surface wave measurements
that uses a non-contact, air-coupled ultrasonic transducer; this receiver is less dependent on …

The early deformations in materials such as creep, plasticity, and fatigue damages have
been proved to have a close relationship with the nonlinear effect of ultrasonic waves …

Improvement of data-driven techniques, specifically machine learning (ML), in material
science turned it into a powerful tool for predicting materials behavior. Accordingly, this study …

Austenitic stainless steels have a wide range of applications in the energy industry, but the
corrosion resistance of these stainless steels can be reduced by sensitization, particularly in …
