Effect of small scale notches on the very high cycle fatigue of AISI 310 stainless steel [PDF]

, 2015
Fatigue behaviour of AISI 310 stainless steel has been investigated up to very high cycles. The fatigue crack initiation sites were found at the surface of the material.

Crack initiation mechanisms and life prediction of GH4169 superalloy in the high cycle and very high cycle fatigue regime

Journal of Materials Research and Technology, 2023
In this study, the high cycle and very high cycle fatigue behavior of the GH4169 superalloy was investigated. The results of the fatigue tests demonstrated that failures in the high cycle fatigue regime were initiated from the material surface, whereas ...

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 ...

Very High Cycle Fatigue Behavior of Austenitic Stainless Steels with Different Surface Morphologies

Metals, 2022
The fatigue behavior of the two austenitic stainless steels AISI 904L and AISI 347 with different surface morphologies, (i) conventionally turned and finally polished, (ii) cryogenic turned using CO2 snow, as well as (iii) cryogenic turned and finally ...

Asymptotic residual stresses in butt-welded joints under fatigue loading [PDF]

, 2016
If a weld toe is modelled as a sharp V-notch angle, the stress distribution near the notch tip is singular. Its intensity can then be quantified by means of Notch Stress Intensity Factors (NSIF), which have been proven to be capable of summarising the ...

The influential factors on very high cycle fatigue testing results

MATEC Web of Conferences, 2018
When the fatigue cycle is extended from high cycle (105~107) to very high cycle (107~109), the fatigue testing results will be more sensitive to the influential factors such as specimen size, specimen surface roughness and the inclusion size.

Damage development under very-high-cycle fatigue regime

PNRPU Mechanics Bulletin, 2020
A method of testing metallic materials using piezoelectric elements under very-high-cycle fatigue (VHCF) regime is described in the paper. The scheme and structure of a high-frequency fatigue machine are discussed. For the experiments, the first mode of resonant longitudinal vibrations is calculated, corresponding to the natural frequency of the ...

Influence of inclusion type on the very high cycle fatigue properties of 18Ni maraging steel [PDF]

, 2017
Nicht verfügbarThe very high cycle fatigue (VHCF) properties of four 18Ni maraging steels were investigated. Ultrasonic fatigue tests were performed on thin sheets with nitrided surfaces at load ratio R = 0.1.

A review of the research on the VHCF test technology for aero-engine typical materials

Hangkong gongcheng jinzhan, 2023
As the most critical and core part of the aircraft, the aero-engine has been serving in extreme environ-ment such as high temperature and high load for a long time. Fatigue failure is one of the main causes of engine structure failure.
