Special Issue Information

Dear Colleagues,

Non-destructive testing (NDT) has undergone decades of evolution with booming developments both in theories and techniques. The application of NDT techniques has been widely applied in civil engineering, mechanical engineering, aerospace engineering, and so on. Although NDT has been applied in several fields and includes a lot of different techniques like ultrasonic testing, eddy current testing, magnetic particle testing, radioactive testing, and so on, it lacks the understanding of the tested results and the actual conditions especially under the in-service lifecycle. The evolution of the internal defects and its corresponding NDT still requests further study, in particular for the complex structures integrated with composite components.

This Special Issue aims to explore the advances of NDT including the theory, techniques, and engineering applications. Rather than concentrating on the, this Special Issue focuses on the NDT of material level and structural level. This Special Issue expects the investigations related to NDT advances from applications in mechanical engineering, civil engineering, numerical studies, and so on.

This Special Issue expects to publish highquality studies in terms of NDT applications and reviews summarizing the advances in recent years. Original, highquality contributions that are not published elsewhere are the target of this Special Issue.

Potential topics include but are not limited to the following:

Advances in sensing techniques
Novel inspection methods for NDT
Structural health monitoring with NDT
Fatigue performance evaluation with NDT system
Advanced NDT system
Embedded NDT system

Abstract

Ultrasonic testing can be used for a nondestructive and rapid determination of material properties. In this study, twelve asphalt mixture samples of four different types were fabricated and used in conventional material property tests and two ultrasonic wave tests. Physical properties such as bulk specific gravity and air void content, mechanical properties such as dynamic modulus and phase angle, and acoustic properties such as wave velocity were measured. Relationships between these properties were established and analyzed as a tool for the future material property determination. In addition, the dynamic modulus and phase angle, measured in a standard laboratory test, were used to construct two master curve models to predict their values at arbitrary temperatures and frequencies. Furthermore, a theoretical model for wave velocity in a linear isotropic viscoelastic material was utilized with measured density, Poisson’s ratio, phase angle and ultrasonic wave velocity to predict the dynamic modulus. Good agreement has been achieved between laboratory measurements and model predictions. It indicates that ultrasonic testing can serve as a rapid method for material property determination.

Insights into Metal Sheet Novelty Detection via Simulated Electromagnetic Ultrasonic Surface Wave

by Yunlai Zhou, Longlong He, Fei Yang and Jingmang Xu

Abstract

Metal sheets have good performance and have been widely used. Different kinds of defects can be generated during the preparation and service of metal plates, which will cause the structural performance of the metal plates to decline, thus requiring structural health monitoring (SHM). This study proposes an electromagnetic ultrasonic (EMUS) surface wave detection technique for metal sheet defects via simulation. The numerical results show that after the excitation parameters of the EMUS transducer are optimized through orthogonal experimental design, the amplitude of the EMUS signal generated is increased by about 80%. The power spectrum density (PSD) of the EMUS response signal is used to detect defects. Compared with the peak-to-peak detection, the accuracy is higher, and the reliability is better. The accuracy of the proposed “central zero-point” method for measuring the time delay of the EMUS signal wave packet is higher than that of the “peak-to-peak amplitude” method and the “vibration starting point” method and is close to the accuracy of the “cross-correlation” method.

Abstract

The development and application of nondestructive testing technology for prestressed reinforced concrete structures in the field of infrastructure construction were summarized in this study via the analysis of relevant literature worldwide. The detection methods, detection principles, and detection instruments in quality evaluation of prestressed reinforced concrete structures were analyzed and compared, based on which, acoustic emission detection technology, impact echo detection technology, ultrasonic detection technology, infrared thermography detection technology, ground-penetrating radar detection technology, piezoelectric transducer detection technology, and X-ray detection technology were summarized. Additionally, the advantages, disadvantages, and application scope of each detection method were focused upon and analyzed comparatively. It is indicated that further improvement in the detection visualization, accuracy, and efficiency for most nondestructive testing technologies is available by optimizing the algorithm and combining artificial intelligence technology with neural network deep learning, precise positioning, and imaging analysis of the quality defects in prestressed reinforced concrete structures. The results of this study can provide technical reference for the further application and research of nondestructive testing technologies in the quality inspection of prestressed reinforced concrete structures.
