Fatigue life evaluation method for turbine blade, involves determining existence of turbine blade within fatigue-life limit, when creep elongation strain is less than specific percentage of initial length of blade |
摘要 |
<p>The method involves determining existence of a turbine blade (10) within a fatigue-life limit, when the creep elongation strain is less than 0.5% of an initial length of the blade, along the longitudinal direction. The turbine blade exceeds the fatigue-life limit, when the creep elongation strain is >=0.5% than the initial length of the blade. An independent claim is also included for creep elongation strain measuring apparatus of turbine blade.</p> |
