Assessing the Very High Cycle Fatigue Behavior and Frequency Effect of Structural Steel Welds
ABSTRACT The very high cycle fatigue behavior of S275J2+N flux‐core arc welded joints was investigated using the ultrasonic fatigue testing method at a loading frequency of 20 kHz. A bespoke specimen design featuring the weld toe was employed to more suitably represent in‐service welded joints than typical ultrasonic fatigue testing specimens.

Short‐term prediction of railway track degradation using ensemble deep learning
Abstract Short‐term prediction of track degradation facilitates flexible and efficient maintenance, thereby meeting the railway system's escalating demands for track safety and smoothness. However, the track condition evolution presents challenges to accurate prediction, with diverse influential factors resulting in heterogeneous degradation patterns ...

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.
