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.

S–N curves established from limiting energy in the case of specimens additively manufactured from AlSi10Mg

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4771-4790, December 2024.
Abstract This study investigates the varying thermal response of additively manufactured specimens made of AlSi10Mg and subjected to cyclic loading. It is well known that the thermal response is driven primarily by the self‐heating effect. The paper explores the possibility of employing thermographic methods to establish an S–N curve for fatigue life ...

Effect of heat treatment on very-high-cycle fatigue performance of EA4T axle steel

Frontiers in Materials
The fatigue performance of EA4T (25CrMo4) axle steel was investigated using small-specimen rotating-bending tests up to 2 × 108 cycles to clarify how heat treatment affected high-cycle and very-high-cycle fatigue (HCF/VHCF) behavior. Five specimen groups,

Bending fatigue behavior of metastable and stable austenitic stainless steels with different surface morphologies

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 12, Page 4755-4770, December 2024.
Abstract The surface morphology has a significant influence on the fatigue behavior of components. For austenitic stainless steels (ASSs), this issue is even more pronounced due to their metastability. Based on the complex deformation mechanisms of metastable ASSs, which include dislocation slip, deformation twinning, and deformation‐induced ...

On the notch sensitivity of as‐built Laser Beam Powder Bed–Fused AlSi10Mg specimens subjected to Very High Cycle Fatigue tests at ultrasonic frequency up to 109 cycles

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4356-4371, November 2024.
Abstract The notch effect significantly influences the fatigue response of components and is particularly relevant for parts produced with additive manufacturing (AM) processes, characterized by complex geometries and possible geometric discontinuities inducing local and critical peak stresses.

Very high cycle fatigue of fiber‐reinforced polymer composites: Uniaxial ultrasonic fatigue

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 9, Page 3083-3115, September 2024.
Abstract This review explores uniaxial ultrasonic fatigue (USF) testing as a common and dependable method for quantifying the extended fatigue life of fiber‐reinforced polymer (FRP) composites. The objective is to explain the complexities governing the fatigue life behavior of FRPs, particularly in the realm of very high cycle fatigue (VHCF) where the ...

Very HIgh Cycle Fatigue (VHCF) behavior of high strength alloys : A literature review

, 2023
Very High Cycle Fatigue (VHCF) response of metallic materials is considered of significance importance, particularly for high- demanding applications. Since it is proved that most of the engineering materials do not exhibit a conventional fatigue limit, but rather display a continuously decreasing stress-life response at longer lifetimes. Consequently,

Coupling life prediction of bending very high cycle fatigue of completion strings made of different materials using deep wise separable convolution

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 7, Page 2381-2395, July 2024.
Abstract This article predicts bending very high cycle fatigue (VHCF) life of three typical nickel‐based alloys SM2550, BG2532, and G3 used for completion strings. Fatigue tests were conducted on the three alloys using an ultrasonic fatigue system at a frequency of 20 kHz.
