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.

Ultrasonic very-high-cycle fatigue of PBF-LBed AlSi10Mg: effects of specimen size, control volume and defect statistics

Frontiers in Materials
The specimen-size effect in very-high-cycle fatigue (VHCF) of additively manufactured (AM) metals arises from the statistical nature of defect-controlled crack initiation.

A Hybrid Framework for Characterizing and Benchmarking Fatigue S‐N Curves in Aluminum Alloys by Integrating Empirical and Data‐Driven Approaches

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 1, Page 44-59, January 2025.
ABSTRACT The complicated and stochastic nature, coupled with uncertainties and data scatter, poses challenges in developing a general fatigue model. This study introduces a hybrid framework that integrates an empirical model with data‐driven approaches, aiming to address data scarcity and streamline the fatigue characterization of aluminum alloys.
