Special Issue Information

Dear Colleagues,

With the continuous development of science and technology, non-destructive evaluation has become the basic technology of structure management and maintenance in the field of industrial production. It plays an important role in ensuring the safe and reliable service of structure, improving the efficiency of management and maintenance, and generating economic benefits.

In this Special Issue, we are aiming to collate studies on all aspects surrounding “The Advances and Applications of Non-destructive Evaluation”. It will be dedicated to new perspectives on topics ranging from nonlinear acoustics and ultrasonic waves to Lamb wave detection, acoustic emission testing, X-ray radiography, magnetic particle testing, and eddy-current testing. It will also highlight advancements in non-destructive detection technology, structural health monitoring, pattern recognition, deep learning models, artificial intelligence, statistical mathematics, signal processing, and data analytics. This Special Issue aims to bridge the gap between theory and real-world implementation. Any original, unpublished work is welcome. If you have an interest in this topic, please let us know.

This study introduces an innovative, non-contact method for classifying the hardness of austenitic stainless steels (grade AISI 304) based on their intrinsic magnetic fields. Utilizing a 3 × 3 matrix sensor system, this research captures weak magnetic fields to produce precise 2D magnetic field maps of the samples. A key advancement is the application of a modified GoogleNet convolutional neural network, optimized with the stochastic gradient descent with momentum algorithm, which achieves exceptional classification accuracy, ranging from 95% to 100%, and median accuracies of 97.5% to 99%. This method stands out by revealing a novel correlation between annealing temperature and magnetic field strength, particularly a pronounced decline in magnetic properties at temperatures near 1000 °C. This observation underscores the sensitivity of magnetic profiles to heat treatments, offering a groundbreaking approach to material characterization. By enabling reliable, efficient, and fully automated hardness evaluation based on magnetic signatures, this work has the potential to transform materials engineering and manufacturing, setting a new benchmark for non-destructive material analysis techniques.

The monitoring and diagnostic system has been suggested as a non-destructive diagnostic method. The structure and operation of the suggested system can be described by the concept of digital shadow (DS). One of the main DS subsystems is a set of sensors properly placed on the monitored object and coupled with a discrete data processing model created in Matlab/Simulink. The discrete model, as another important DS subsystem of the monitored facility, transfers information about its technical condition to the operator based on data recorded by the sensor system. The digital monitoring model processes the recorded data in the form of the object’s response to actions caused by its operating conditions. This work formalized a mathematical model determining the coupling of the digital model with the sensors placed on the monitored object. The formulated method using DS, due to its sensitivity, enables the detection of the damage in the object at an early stage. The tests allowed for detecting the regularities enabling the determination of the area of damage to the shaft and its size. Full article
