Development of a Probabilistic Model for the Prediction of Fatigue Life in the Very High Cycle Fatigue (VHCF) Range Based on Inclusion Population [PDF]

Advanced Materials Research, 2014
The aim of the present work is to develop a statistical approach for the correlation between the quality of metallic materials with respect to the size and arrangement of inclusions and fatigue life in the VHCF regime by using the example of an austenitic stainless steel AISI 304.

Fatigue Behavior of Metastable Austenitic Stainless Steels in LCF, HCF and VHCF Regimes at Ambient and Elevated Temperatures

Metals, 2019
Corrosion resistance has been the main scope of the development in high-alloyed low carbon austenitic stainless steels. However, the chemical composition influences not only the passivity but also significantly affects their metastability and ...

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 ...

Microscopic Damage Evolution During Very High Cycle Fatigue (VHCF) of Tempered Martensitic Steel

Procedia Engineering, 2016
AbstractDimensioning of high-strength steels relies on the knowledge of Wöhler-type S/N data and the assumption of a fatigue limit for applications where the number of load cycles exceeds 107. Very high cycle fatigue (VHCF) experiments applied to a 0.5C-1.25Cr-Mo tempered steel (German designation: 50CrMo4) revealed surface crack initiation at prior ...

Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]

MATEC Web of Conferences, 2018
Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

Ultrasonic VHCF Tests on Very Large Specimens with Risk-Volume Up to 5000 mm³

Applied Sciences, 2020
The research on the size-effects in Very-High-Cycle Fatigue (VHCF) has recently drawn the attention of several scholars. The fatigue cracks in VHCF originate from the largest defect present within the loaded material volume (risk-volume) and the larger ...

Investigation of the damage mechanisms during very high cycle fatigue (VHCF) of a tempered carbon steel

Procedia Structural Integrity, 2016
AbstractThe study is an overview of recent investigations dealing with the fatigue damage in the HCF and VHCF regime of 0.5C-1Cr martensitic steel (German designation: 1.7228) in a tempered condition. The experimental part is focussed on the microstructural characterization regarding crystallographic orientation, reconstruction and grain size ...

Simulation of microstructural damage evolution during very high cycle fatigue (VHCF) using the boundary element method [PDF]

PAMM, 2013
AbstractA simulation model for damage evolution in slip bands under VHCF condition is presented. By use of a numerical method it is applied to a real simulated microstructure of AISI304. It considers orientations of slip systems as well as individual anisotropic elastic properties in each grain.

Very high cycle fatigue (VHCF) response of an Additively manufactured Nitinol

International Journal of Fatigue
This work investigates the Very High Cycle Fatigue (VHCF) response of an Additively Manufactured (AM) Nitinol alloy. To resemble in-service loading conditions of typical Nitinol components, an innovative experimental setup has been proposed, where the martensite/austenite transformation fraction is controlled by applying a mean static compressive load ...
