A statistical analytical method for fatigue reliability containing very-high-cycle fatigue regime [PDF]

open access: yes, 2013
Fatigue tests usually cost a lot of time and expenses especially for very-high-cycle fatigue(VHCF).Hence,a convenient and fast method is necessary for obtaining the S-N curve under different probabilities(i.e.P-S-N curve) s that to give an entire trend ...

Characterising the impact of surface integrity on the fatigue behaviour of a shot-peened connecting rod [PDF]

open access: yes, 2014
The present study focuses on analysing and modelling the influence on fatigue behaviour of the surface of a hot-forged C70 connecting rod which undergoes a shot-blasting treatment.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Study on high-cycle fatigue and very-high-cycle Fatigue properties for braided composites

open access: yesJournal of Physics: Conference Series
Abstract Braided composite materials are widely used in structures such as aircraft engine blades due to their unique advantages of integrity and damage resistance. Their fatigue performance is an important indicator for the development of aircraft engines.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

A probabilistic high cycle fatigue model applied to cast Al-Si alloys [PDF]

open access: yes, 2013
In this work, the high cycle fatigue behavior of cast hypo-eutectic Al-Si alloys is investigated. It is observed that two different coexisting fatigue initiation mechanisms can occur in these materials depending on the presence of different ...

Correlation of crack growth rate and stress ratio for fatigue damage containing very high cycle fatigue regime

open access: yes, 2012
A model is proposed to correlate the crack growth rate and stress ratio containing very high cycle fatigue regime. The model is verified by the experimental data in literature.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

A cumulative damage model for fatigue life estimation of high-strength steels in high-cycle and very-high-cycle fatigue regimes

open access: yes, 2012
A cumulative fatigue damage model is presented to estimate fatigue life for high-strength steels in high-cycle and very-high-cycle fatigue regimes with fish-eye mode failure, and a simple formula is obtained.
