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.

Tuning residual stresses in welded structures by exploiting bio‐inspired suture interfaces
Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4560-4572, December 2024.Abstract Nature offers a valuable source of inspiration when designing optimized structures. For instance, when two or more shells are joined during growth processes, Nature prefers to exploit interlocking paradigms to enhance the strength of the bond—cranial sutures are one example.
