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 …

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 …

This paper presents a computationally efficient time-domain spectral finite element method
(SFEM) and a crack model to take into account guided wave propagation, scattering and …

Most reported research for monitoring health of pipelines using ultrasonic guided waves
(GW) typically utilize bulky piezoelectric transducer rings and laboratory-grade ultrasonic …

The unusual topology of elastic waves in continuum systems has been recently uncovered.
Prominently, the spin of Rayleigh-Lamb waves has been experimentally observed and used …

Guided wave testing is one of non-destructive testing techniques for pipeline inspection
using low-frequency ultrasonic waves. Guided wave testing uses a set of equally placed …

Pipeline systems, such as oil and natural gas pipelines, which are normally buried
underground or distributed under the sea, are susceptible to corrosion and pressure …

In order to improve the performance of the conventional guided wave testing (GWT) with a
low sensitivity on damage in pipelines, a new GWT based on time-frequency-domain …

An axisymmetric guided wave mode is excited independently within a circular tube structure
to reduce the complexity of signal interpretation through the prevention of unwanted wave …

The development of ultrasonic‐guided wave sensors is of great significance for structural
health monitoring (SHM). In this work, a shear horizontal (SH) ultrasonic guided wave …
