fe-safe/TURBOlife™ features

Component Loading

• time histories of stresses and temperatures calculated in an elastic FE analysis

Stress-strain modelling

• transition from monotonic to cyclic behaviour
• multiaxial plastic relaxation rules to estimate the actual stress and strain from the elastic stress
• creep materials data enhanced using the Larson-Miller parameter for interpolation and logarithmic extrapolation

Damage Calculation

• thermo-mechanical fatigue damage, creep damage, and fatigue-creep interaction
• damage for each individual cycle, including damage for uncompleted cycles
• advanced treatment of multiaxial stresses
• creep damage for each time increment is calculated from the creep strain increment and the creep ductility as a function of creep strain rate

Output

• fatigue life and creep life contour plots for the component
• creep damage and fatigue damage for the entire loading history is cross-plotted as a damage trajectory on the creep-fatigue damage envelope to indicate creep-fatigue interaction effects
• stress ranges and strain ranges of complete cycles and part-cycles for selected locations
• cumulative creep damage, cumulative fatigue damage, cumulative creep strain, instantaneous stress, instantaneous strain, instantaneous creep strain rate, plotted as a function of time for selected locations

fe-safe/TURBOlife™ creep-fatigue methodology is based on ductility exhaustion concepts which have been developed over the past 25 years in the United Kingdom. These methods are used extensively throughout the nuclear and fossil fuel power generation industries. fe-safe/TURBOlife™ algorithms have been specifically developed for flexibility in their application. They are also used for continuous monitoring applications on power station boilers and gas turbines. fe-safe/TURBOlife™ is supported by highly experienced assessment engineers and extensive materials testing laboratories at Serco Assurance, Risley, UK. fe-safe/TURBOlife™ is easy to learn and easy to use. Designs can be optimised rapidly, development times shortened, material costs reduced and the final design verified on the computer, giving confidence that it will pass test schedules as right-first-time.
