The development of structural health monitoring (SHM) techniques is of great importance to
improve the structural efficiency and safety. With advantages of long propagation distances …

The development of structural health monitoring (SHM) systems and their integration in
actual structures has become a necessity as it can provide a robust and low-cost solution for …

Transverse cracks in the rail foot are responsible for the breaking of the rail. The existing non-
destructive testing technology for high-speed railway track is difficult to perform in-situ and …

Delamination is the most common and dangerous failure mode for multilayered structures.
Delamination defects of different shapes and sizes have different sensitivity to guided wave …

This article provides a quantitative nondestructive damage detection method through a
Lamb wave technique assisted by an artificial neural network model for fiber-reinforced …

This paper presents two algorithms, both based on the time of flight (ToF) of scattered
waves, to locate defect in an anisotropic woven-fabric carbon fiber reinforced polymer …

This paper proposes a damage assessment approach for composites based on the Lamb
wave factorization method. It can exploit both the forward and back-scattering waves and …

A new experimental procedure for damage detection based on active acoustic emission was
developed which is sensitive to damage depth. Two new damage indexes were proposed …

Composite materials are prone to impact damage, which affects structural stability and
causes safety concerns. Due to the complexity and diversity of them, the damage …

The air-coupled ultrasonic technique is capable of detecting defects in in-service CFRP
plates and ensuring their application safety. Traditional air-coupled ultrasonic methods often …
