Fatigue behaviour of SiC p -reinforced aluminium composites in the very high cycle regime using ultrasonic fatigue [PDF]

, 2006
The fatigue behaviour of a 2009/SiC/15p-T4 DRA composite has been examined in the very high cycle fatigue (VHCF) regime where 10 7 ≤ N f ≤ 10 9 cycles. Ultrasonic fatigue was used to achieve the very high cycle counts.

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.

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,

Effect of defect size on P-S-N curves in Very-High-Cycle Fatigue [PDF]

, 2017
It is well-known that internal defects play a key role in the Very-High-Cycle Fatigue (VHCF) response of metallic materials. VHCF failures generally nucleate from internal defects, whose size strongly affects the material strength and life.

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 ...

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 (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,
