Guided Wave for plate inspection
Guided wave ultrasonic testing (GWT) for plate inspection presents a valuable non-destructive evaluation technique for monitoring large, inaccessible structural components such as petrochemical tank floors and dam penstock gates. Unlike traditional spot-

Shear-horizontal guided wave tomography [PDF]
The petrochemical industry’s pipe-network is increasingly suffering from corrosion-induced shutdowns and thus a quantitative measurement approach is vital for making adequate service-life predictions and to guarantee safety. At pipe-supports, access is

Ultrasonic guided wave detection of U-shaped pipeline [PDF]
The guided waves in the elbow was analyzed using semi- analytical finite element method, which was used to calculate the dispersion curves, along with the vibration deformation and energy flow density distribution of the elbow cross-section.

Study on Bond Defect Detection in Grouted Rock Bolt Systems under Pullout Loads
In grouted rock bolt systems, bond defects often occur, which seriously affects the safety of rock mass structures. Therefore, in this study, based on the existence of bond defects, laboratory tests were conducted to detect the location and length of ...

Transversely periodic solitary-wave solutions of the Boussinesq equations (which govern wave propagation in a weakly dispersive, weakly nonlinear physical system) are determined. The solutions for negative dispersion (e.g., gravity waves) are singular and therefore physically unacceptable. The solutions for positive dispersion (e.g., capillary waves or

Propagation of Waves in Helical Wave Guides [PDF]
The field configuration near the conductors of a helical wave guide is obtained from the solution of the spatial-wave equation for a developed helix. This solution is first obtained for the case of tape conductors and then adapted to elliptical (including circular) conductors by conformal transformation.
