Summary

The ultrasonic detection technique is a very promising method for non-destructive testing (NDT) and structural health monitoring (SHM). Ultrasonic imaging is a key method for characterizing damages in complex structures (such as concretes, composites, and rails). Phased array ultrasonic testing (PAUT) has significant advantages in beam control, dynamic focusing, and visualization imaging. Ultrasonic guided waves (UGW) can be used for long-distance and large-scale monitoring of structures (such as pipelines, rails, and composites). Air coupled ultrasonic testing (ACUT) does not require liquid coupling or direct contact with the test object, making it a promising technology in the detection of sensitive materials (such as aerospace composites). Shear wave imaging based on dry point contact (DPC) ultrasonic sensors is widely used for detecting defects in concrete structures. Ultrasonic wavefield imaging (UWI) utilizes full field ultrasound measurements and advanced reconstruction algorithms to provide comprehensive spatial and temporal visualizations of the interaction between waves and defects. Laser ultrasonic testing can achieve a non-contact, high spatiotemporal resolution detection of structural surface defects. This Special Issue aims to provide highlight new research on the recent advances, technologies, solutions, applications in the field of ultrasonic sensors for SHM. Specific topics of interest include, but are not limited to, the following key areas:
- High resolution ultrasonic imaging of complex structures
- Ultrasonic NDT of concrete structures
- Ultrasonic NDT of composites
- Ultrasonic NDT of railway infrastructures
- Ultrasonic phased array for defect detection
- Ultrasound image reconstruction based on deep learning
- Wave–material interaction
- Integration of artificial intelligence (AI) with acoustic-based SHM
