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.

On Crack Initiation and Early Growth of Very-High-Cycle Fatigue for High Strength Steels

, 2012
In the regime of Very-High-Cycle Fatigue (VHCF) for high strength steels, crack initiation and early growth dominate the fatigue life. The process of crack initiation and early growth of high strength steels at VHCF regime almost originates from the ...

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 ...

Numerical investigation of the influence of shear band localization on the resonant behavior in the VHCF regime

Theoretical and Applied Mechanics Letters, 2014
The monitored resonant behavior of fatigue specimens of metastable austenitic stainless steel (AISI304) is correlated with its damage accumulation in the very high cycle fatigue (VHCF) regime.

The Effect of Microstructure on the Very High Cycle Fatigue Behavior of Ti-6Al-4V Alloy

Metals
Crack initiation plays a major role in very high cycle fatigue (VHCF) life, and the initiation of cracks is related to slip behavior. There is a need for improvement in the understanding of the influence of Ti-6Al-4V microstructures on VHCF performance ...

Effects of loading condition on very-high-cycle fatigue behaviour and dominant variable analysis

, 2014
The specimens of a high carbon chromium steel were quenched and tempered at 150A degrees C, 180A degrees C and 300A degrees C. Such specimens were tested via rotating bending and a push-pull type of axial loading to investigate the influences of loading ...

Simulation of Deformation-induced Martensite Formation and its Influence on the Resonant Behavior in the Very High Cycle Fatigue (VHCF) Regime

Procedia Materials Science, 2014
AbstractThe exploration of fatigue mechanisms in the VHCF regime is gaining importance since many components have to withstand a very high number of loading cycles due to high frequency or long product life. In this regime, particular attention is paid to the period of fatigue crack initiation and thus the localization of plastic deformation.
