For the monitoring of plate structures, phased array guided wave has great application
prospects to effectively determine damage location and size. Locating damage via phased …

This paper presents a local defect resonance (LDR)-based approach to detect barely visible
impact damages (BVIDs) in woven CFRP laminates using laser-ultrasonic guided waves. In …

This paper presents a new structural health monitoring strategy based on a deep learning
architecture that uses nonlinear ultrasonic signals for the automatic assessment of breathing …

This paper aims to investigate the use of ultrasonic guided wave (GW) propagation
mechanism and the assessment of debonding in a sandwich composite structure (SCS) …

Local wavenumber estimation (LWE) applied to a full wavefield response is a powerful
approach for detecting and characterizing defects in a composite structure. However, the …

The paper concerns assessing the quality of the adhesive connection between a steel plate
and the reinforcing CFRP laminate. A three-stage algorithm for non-destructive damage …

Ultrasonic pulse-echo C-scan imaging is a widespread method for detecting and
characterizing defects in fiber reinforced polymer composites. However, the accurate …

The structural integrity and safety of carbon fiber reinforced plastics (CFRP) are vulnerable
to delamination, which is often imperceptible to the naked eye. Although the Scanning Laser …

Damage in structures can cause local anomalies in a guided wavefield due to reflection of
guided waves in neighborhoods of damage. These local anomalies can be used for …

Delamination is a type of damage frequently occurring in laminated composite plates.
Delamination detection is crucial to ensure structural integrity and safety. This paper …
