Oil and gas pipelines are very important for fuel transportation, however leakages in them
may lead to life and property losses due to the release of the energy they contain. Reliable …

Eddy current pulsed thermography (ECPT) has been used in the characterization of Rolling
Contact Fatigue (RCF) cracks in rail by taking advantage of electromagnetic thermal …

Transverse cracks in the rail foot are responsible for the breaking of the rail. The existing non-
destructive testing technology for high-speed railway track is difficult to perform in-situ and …

We propose a new unidirectional point focusing shear horizontal (SH) guided wave
electromagnetic ultrasonic transducer (EMAT) with an angled periodic permanent magnet …

Understanding of optimal signal generation and frequency content for electromagnetic
acoustic transducers (EMATs) is key to improving their design and signal to noise ratio …

Many surface breaking defects, such as those caused by thermal fatigue or stress corrosion,
have finite lateral dimensions. However, much of the research considers significantly larger …

Due to the simple wave structure and low-attenuation and non-dispersive properties, the
lowest-order shear horizontal mode SH 0 can realize the efficient large-scale damage …

A circumferential crack in the fusion line is a major threat to the structural integrity of the
pipeline girth weld because it may possibly lead to fracture failure when subjected to large …

In ultrasonic testing field, the design and optimization of point-focusing shear vertical waves
electromagnetic acoustic transducer (PFSV-EMAT) with high energy conversion efficiency …

Although ultrasonic focusing methods have been widely used in electromagnetic acoustic
transducers (EMATs) to solve the problem of their low energy conversion efficiency, the …
