Shear horizontal (SH) waves are of great importance in structural health monitoring (SHM)
and nondestructive testing (NDT), since the lowest order SH wave in isotropic plates is non …

Ultrasonic guided wave techniques are extensively applied in the non-destructive testing
and structural health monitoring (SHM) of oil and gas pipelines due to its advantages of wide …

Delamination in composite structures is characterized by a resonant cavity wherein a
fraction of an ultrasonic guided wave may be trapped. Based on this wave trapping …

We propose an outlier detection‐based statistical approach to identify and locate a defect in
composite plates using far fewer number of sensing points compared to conventional …

The detection of corrosion in insulated pipes is of major importance to the oil and chemical
industries. Current methods involving point-by-point inspection are expensive because of …

Damage is an inevitable occurrence in metallic structures and when unchecked could result
in a catastrophic breakdown of structural assets. Non-destructive evaluation (NDE) is …

This paper deals with a semi-analytical finite element (SAFE) method for modeling wave
propagation in waveguides of arbitrary cross-section. The method simply requires the finite …

Guided acoustic and ultrasonic waves have been utilized in various manners for non-
destructive evaluation and testing. If a guided wave mode is dispersive, a pulse of energy …

This work presents the feasibility of monitoring state of charge (SoC) and state of health
(SoH) of lithium-ion pouch batteries with acousto-ultrasonic guided waves. The guided …

The dispersion of ultrasonic guided waves causes wave-packets to spread out in space and
time as they propagate through a structure. This limits the resolution that can be obtained in …
