Pipelines are major structures for transporting the liquid or gaseous products and their safe
operation is dependent upon the maintenance of structural integrity of the system. Leaks in …

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 …

Turbine blades and nozzle guide vanes (NGVs) are operated at extreme temperatures in
order to maximise thermal efficiency and power output of an engine. In this paper the …

This paper reports on a new means of generating higher-order mode clusters of guided
waves (HOMC-GW) using a meander-coil (MC) electromagnetic acoustic transducer (EMAT) …

Corrosion detection in the annular plate region of above-ground storage tanks is a critical
need for tank farm operators in the oil and gas industry. The critical zone between the tank …

Abstract Higher Order Modes Cluster (HOMC) guided waves are non-dispersive wave
packets consisting of higher order Lamb wave modes. This paper investigates the effect of …

Higher Order Mode Cluster (HOMC) guided waves (GW) have recently been proposed for
ultrasonic testing of plates and pipes. The incident wave through the plastic wedge …

In recent years, Higher Order Modes Cluster (HOMC) guided waves have been considered
for ultrasonic testing of plates and pipes. HOMC guided waves consist of higher order Lamb …

Pipelines play a major role in transporting substances, especially oil and gas. However,
maintaining the steady health of the massive, long structure of pipelines is very challenging …

The paper discusses the numerical modeling of ultrasonic high frequency guided waves
(HFGW) for nondestructive inspection of main vessel core support structure (MV-CSS) in …
