Finite element analysis is used for stress analysis, but this does not answer the most important questions - How long will the component last in service? What design changes are needed to provide optimum durability? How does elevated temperature service reduce durability? What is the cause of failure – creep, fatigue, or creep-fatigue interaction?
fe-safe/TURBOlife™ provides the answers. It is a powerful, comprehensive and easy-to-use suite of creep-fatigue analysis software for finite element models. It has direct interfaces to leading suites of FEA software.
fe-safe/TURBOlife™ calculates
The results are presented as contour plots of creep-fatigue lives, and stress safety factors for a specified design life. These can be plotted using standard FEA viewers or other leading graphics software.
fe-safe/TURBOlife™ creep-fatigue algorithms have been successfully applied to nuclear power plant components, power station boilers, gas turbine blades, steam turbine components, automotive exhaust components and turbocharger impellers.
fe-safe/TURBOlife™ calculates the endurance of components in high temperature environments where fatigue damage mechanisms and creep damage mechanisms interact to significantly reduce component life.
fe-safe/TURBOlife™ works from elastic finite element analysis and easily 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™ identifies whether fatigue and/or creep are the dominant damaging mechanisms, thus enabling re-design to focus on the relevant damage mechanisms and significantly reduce pre-service component testing.
fe-safe/TURBOlife™ provides comprehensive graphical output in terms of life contours and stress safety factors enabling critical areas to be easily identified.
fe-safe/TURBOlife™ includes comprehensive on-line help and information on materials data preparation.
