The wear and rolling contact fatigue (RCF) testing approaches for wheels and rails have
been reviewed and evaluated in this study. The study points out the advantages and …

This paper discusses a non-destructive evaluation (NDE) technique for the detection of
damage in composite aircraft structures following high energy wide area blunt impact …

Ultrasonic guided wave is widely used to detect cracks in rail because of its long
propagation distance and small attenuation. To effectively detect the fatigue crack in rail …

This paper presents a hybrid method to assess the rail health with the focus on a specific
type of rail surface defect called head check. The proposed method uses physics-based and …

As a key equipment in high-speed railway operation, rails inevitably produce various fatigue
cracks during long-term service, which are major safety hazards in the railway …

Ultrasonic rail inspection is the most commonly implemented method for detecting internal
rail defects. While the conventional ultrasound wheel probe has gained its popularity within …

Rail internal defects have been one of the major causes of train derailments in the US. While
the conventional ultrasound wheel probe has been widely implemented for rail track …

Non-destructive Evaluation (NDE) is the process of using non-invasive procedures to
inspect or characterize an object without altering its form, fit, or function. Ultrasonic testing is …
