In this study, we propose a straightforward and easy-to-use method (chirp guided wave
mixing, CGWM) for detecting delaminations in CFRP laminates. In this method, two long …

Ultrasonic inspection is a widely used nondestructive testing approach in industrial fields for
more accurate life prediction and efficient management strategies of critical structural …

Various types of defects can be induced during the manufacturing or operation of
engineering structures. For effective detection and characterization of the defects in large …

Linear and nonlinear ultrasonic guided wave (UGW)-based methods are available for
fatigue crack detection and quantification. However, linear methods usually fail to detect …

The resonance behaviors of defects, specifically local defect resonance (LDR), are useful for
defect detection in structures. However, there is a lack of intuitive elucidation regarding the …

In this paper, nonlinear Lamb waves with phase-velocity mismatching are proposed to
detect accurately closed cracks by excluding the intrinsic material nonlinearity. Simulations …

In this study, the fast multipole indirect boundary element method (FM-IBEM) was adopted
for solving the scattering problem of incident P-waves using a two-dimensional (2D) …

In order to improve the spatial resolution and the signal-to-noise ratio of Lamb waves in
structural health monitoring systems or non-destructive testing techniques, this study …

This study uses Scholte waves to characterize the interfacial stiffness of a film–substrate
structure. A theoretical model was formulated to investigate the dispersion relationships of …

Beyond the detectability of ordinary nondestructive evaluation (NDE) and structural health
monitoring (SHM) methods, microscopic damage, as typified by embryonic fatigue cracks …
