The paper provides a state of the art review of guided wave based structural health
monitoring (SHM). First, the fundamental concepts of guided wave propagation and its …

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 …

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 …

Guided wave inspection has proven to be a very effective method for the rapid inspection of
large structures. The fundamental shear horizontal (SH) wave mode in plates and the …

Inspection for corrosion and pitting defects in the petrochemical industry is vital and forms a
significant fraction of the operating expenditure. Low frequency guided wave inspection is …

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 …

Topographical features such as welds, stiffeners, and bends in plate-like structures have
been identified as special local waveguides, which are able to render ultrasonic wave …

Guided wave inspection is used extensively in petrochemical plants to check for defects
such as corrosion. Long-range low-frequency inspection can be used to detect relatively …

Thickness reduction arising due to corrosion or in any other ways can cause severe
damages to structures. Hence regular inspection of structures is vital in many industries. One …

An optimized dictionary of matching pursuit (MP) is designed and combined with the
ultrasonic guided wave for characterizing pipeline defect, which consequently achieves …
