Low-cycle fatigue calculation of gas turbine engine disks under flight cycle conditions
We address the effects of the actual flight cycle for gas turbine engine disks, which is influenced by low-cycle fatigue. An approach is proposed which improves reliability of life cycle prediction owing to schematization of flight cycle with a criterion for reaching the maximum intensity of total s...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We address the effects of the actual flight cycle for gas turbine engine disks, which is influenced by low-cycle fatigue. An approach is proposed which improves reliability of life cycle prediction owing to schematization of flight cycle with a criterion for reaching the maximum intensity of total strain range. Contribution of subcycles to the cumulative damage is demonstrated. |
