Very high cycle fatigue strength and crack growth of thin steel sheets [PDF]
Fracture and Structural Integrity, 2016 For basic observations or for industrial applications it is of interest to use flat specimens at very high frequency in the gigacycle regime. In this work, thin flat sheet, with 1.2 mm thickness of a complex phase ferrite-martensitic steels were ...

Damage evolution in the AlMg6 alloy during high and very high cycle fatigue
Fracture and Structural Integrity, 2019 Paper presents the “in situ” method for determining of irreversible fatigue damage accumulation, based on the analysis of nonlinear manifestations of the feedback signal in a closed system of an ultrasonic fatigue system.

Fretting Fatigue Behaviour of Alloy Steel in the Very High Cycle Region [PDF]
MATEC Web of Conferences, 2019 It is well known that fretting fatigue strength is much lower than the fatigue strength of smooth specimens and the fatigue limit disappears. Many studies on fretting fatigue have been reported but most of the studies have not cover fatigue properties in

Very High Cycle Fatigue Behavior of TA11 Titanium Alloy
Journal of Aeronautical Materials, 2017 The conventional fatigue test method was used to obtain the very high cycle fatigue (VHCF) limits of 3×107 and 1×108 cycles for TA11 titanium alloy in different temperatures and stress ratios.

Comparison between Fractal and Statistical Approaches to Model Size Effects in VHCF
Metals, 2022 Size effects concern the anomalous scaling of relevant mechanical properties of materials and structures over a sufficiently wide dimensional range. In the last few years, thanks to technological advances, such effects have been experimentally detected ...

Effect of Loading Frequency on the Fatigue Response of Adhesive Joints up to the VHCF Range
Applied Sciences, 2023 Modern structures are designed to withstand in-service loads over a broad frequency spectrum. Nonetheless, mechanical properties in numerical codes are assumed to be frequency-independent to simplify calculations or due to a lack of experimental data ...
