Long-range guided wave testing is a well-established method for detection of corrosion
defects in pipelines. The method is currently used routinely for above ground pipelines in a …

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 …

Recent bone quantitative ultrasound approaches exploit the multimode waveguide
response of long bones for assessing properties such as cortical thickness and stiffness …

Nondestructive evaluation (NDE) of the mechanical properties and thickness loss of coated
structures is of great importance for health monitoring purposes. This study aimed to …

A study on guided waves in a layered half-space with large velocity contrasts and a
decreasing velocity with depth is presented. Multiple mode dispersion curves are calculated …

Long-range guided wave testing (GWT) is used routinely for the monitoring and detection of
corrosion defects in above ground pipelines. The GWT test range in buried, coated pipelines …

Guided wave propagation theories have been widely explored for about one century. Earlier
theories on single-layer elastic hollow cylinders have been very beneficial for practical …

Guided waves propagating in lossy media are encountered in many problems across
different areas of physics such as electromagnetism, elasticity and solid-state physics. They …

Guided waves, consistent with the A0 Lamb mode, have previously been observed in bone
phantoms and human long bones. Reported velocity measurements relied on line fitting of …

The configuration of magnetostrictive transducers for both transmitter and receiver was
optimized for the generation and reception of ultrasonic longitudinal guided waves in seven …
