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.

VHCF Behavior of Welded Joints with HFMI Treatment under Moisture Conditions

Welding Journal, 2022
Fatigue tests of cruciform welded joints made of Q355B steel at very-high-cycle fatigue (VHCF) regimes were carried out on as-welded specimens using high-frequency mechanical impact (HFMI) treatment in dry air and water-spray environments, respectively. The influence of the environment on fatigue life was more obvious in the VHCF regime.

VHCF Response of H13 Steels Produced with Different Manufacturing Processes

Procedia Engineering, 2016
AbstractExperimental results have recently shown that failures at stress amplitude below the conventional fatigue limit and at Very High Cycle Fatigue (VHCF) are possible. In case of high-strength steels, VHCF failures generally originate from defects/inclusions present within the material and, consequently, the defect population properties (size and ...

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.

Fatigue Crack Segmentation and Characterization of Additively Manufactured Ti‐6Al‐4V Using X‐Ray Computed Tomography

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 1, Page 204-216, January 2025.
ABSTRACT X‐ray computed tomography (XCT) is extremely useful for the non‐destructive analysis of additively manufactured (AM) components. AM components often show manufacturing defects such as lack‐of‐fusion (LoF), which are detrimental to the fatigue life of components.
