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 aims to provide an overview of the experimental and simulation works focused
on the detection, localisation and assessment of various defects in pipes by applying fast …

This paper presents an improved numerical strategy for the broadband analysis of wave
propagation in composite or complex cross-sectional waveguides using the wave finite …

The drinking water mains, mostly buried underground and stay there for decades, require
proper maintenance to prevent failures. Among different kinds of material, polyvinyl chloride …

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 identification of structural damage in composite waveguides is a critical issue in
aerospace and transportation industries. Frequently, these structures involve periodic …

This paper represents the second part of the work that considers the identification and sizing
of machined defects in a pipeline. This study deals with the torsional-mode reflection from …

A steel pipeline of about 60 m long containing several pipes and structural singularities
(bends, welds, clamps, etc.) is inspected in this work using a guided-waves technique. The …

As a common kind of failure, crack damages account for major losses in plastic pipeline
systems, which are now increasingly being used. In this study, a crack detection method for …

With the rapid development of the economy and society, non-metallic pipelines are more
and more widely used in oil and gas fields, water supply projects, urban gas systems, and so …
