To provide an opportunity for the global fatigue community to present and discuss the latest experimental and theoretical research on the fatigue behavior of structural materials in the very high cycle regime. View the Keynote Speakers.
|TECHNICAL SCOPE AND TOPICS
In recent years, there has been a growing emphasis on safely extending the service lives of existing transportation and power generation systems beyond their original design lifetimes.
The need to reduce environmental impact and the need for increased economic efficiency are driving the design of new components and systems in which fatigue lifetimes as long as 109 to 1010 cycles are required. Thus, there is global interest in, and need for, improved understanding of the fatigue behavior of structural materials in the very high cycle fatigue (VHCF) regime.
- Mechanisms of crack initiation and crack propagation at very long lifetimes and the role of microstructure, defects and environment on these phenomena
- Fatigue life variability and its dependence on microstructure variability in the very high cycle regime
- Effect of variable amplitude loading on high cycle fatigue (HCF) damage
- Statistical and probabilistic modeling of very long life fatigue behavior and the
development of life prediction models
- Similarities and differences between life-limiting behavior in HCF and VHCF
- Environment and temperature effects on VHCF behavior
- Surface modification and other methods to improve VHCF behavior
- Assessment and modeling of fatigue damage accumulation in VHCF regime
- Fatigue threshold, nonpropagating cracks and fatigue limits at very long lifetimes
- Growth of small and short cracks
- Instrumentation and experimental methods for fatigue research in the very high cycle regime
- Fatigue design and damage detection at very long lifetimes
- New materials and methods for improved fatigue performance in the very high cycle regime
- Case studies of fatigue failure at very long lifetimes
- Prognosis and structural materials health management in the VHCF regime
