METHOD FOR ESTIMATING THE CONSUMED LIFE OF A ROTATING COMPONENT

The method for estimating the consumed life of a rotating component comprises providing an initial component lifetime, providing a first relationship between local creep elongations measured at multiple locations (10, 11, 12, 13) of the component (6) and a combined creep elongation, which is indicat...

More Information
Summary:The method for estimating the consumed life of a rotating component comprises providing an initial component lifetime, providing a first relationship between local creep elongations measured at multiple locations (10, 11, 12, 13) of the component (6) and a combined creep elongation, which is indicative of the local creep elongations substantially irrespective of the operating conditions, measuring the local creep elongations at the multiple locations of the component, based on the measured local creep elongations, calculating the combined creep elongation, providing a second relationship between the combined creep elongation and a consumed life, estimating based on the second relationship and the calculated combined creep elongation the consumed life.
