fe-safe/TURBOlife identifies whether fatigue and/or creep are the dominant damaging mechanisms, thus allowing re-design to focus on the relevant damage mechanisms and significantly reduce pre-service component testing.
fe-safe/TURBOlife works from elastic finite element analysis and widely available materials data to construct complex, stress-strain hysteresis loops including stress relaxation due to creep. In this way, component-specific operating histories and the order of cycling are comprehensively accounted for.
fe-safe/TURBOlife creep-fatigue methodologies are based on the Ductility Exhaustion concepts and Strain Range Partitioning which have been developed over the past 25 years in the United Kingdom and the United States. These methods are used extensively throughout the nuclear and fossil fuel power generation industries for new designs and for continuous monitoring of applications on power station boilers and gas turbines.
- Where fatigue cracks will occur
- When fatigue cracks will occur
- How creep mechanisms will influence fatigue life
- Factors of safety on working stresses - for rapid optimization
- The endurance of components in high temperature environments where fatigue damage mechanisms and creep damage mechanisms interact to significantly reduce component life
- Whether fatigue damage is caused predominantly by fatigue, creep or creep-fatigue interactions
fe-safe/TURBOlife is an add-on module to fe-safe, enabling users to include the effects of complex loading histories, multiaxial fatigue, and other advanced capabilities in fe-safe.
