HOW TO DO RLA STUDY OF TURBINE
Turbine is the most critical equipment operated in hi temperature and speed. Stress is developed due to fluctuation in temperature and frequent start// stop of the machine. If the operating temperature and differential temperature go beyond permissible limit , stress is developed.In real life situation, a component experiences combination of loading patterns whereby its life is consumed by a combination of creep damage, low cycle fatigue damage and crack propagation. Minor's sum is used to determine the life of the component under various kinds of loading patterns expected to be encountered by the component during its life span. The testing plan (typical) for turbine as per below fig.
