Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects
Strain, Volume 61, Issue 2, April 2025.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.
