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 …

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 …

Guided ultrasonic waves have been successfully applied to detect defects and corrosion in
plates and pipes; however, defect sizing remains challenging due to the complex profiles of …

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 …

This research utilizes Ultrasonic Guided Waves (UGW) to inspect corrosion-type defects in
steel pipe walls, providing a solution for hard-to-reach areas typically inaccessible by …

Corrosion is a chemical reaction affecting a wide range of materials. Safety-critical structures
in the oil, gas, petrochemical, and many other industries need a fast, reliable screening …

Hidden corrosion defects can lead to dangerous accidents such as leakage of toxic
materials causing extreme environmental and economic consequences. Ultrasonic guided …
