| Abstract: |
| The endurance life experiments are made on the specimens cut from the typical part of the turbine blades with the film cooling holes (perpendicular-hole and nonperpendicular-hole). The experimental results show that the film cooling holes have a significant influence on endurance life compared with standard specimens’ one. To validate these results, FEA simulation is carried out using the orthogonal anisotropic property and creep law under high temperature. Moreover, the endurance life is obtained by computing the maximum stress value and its location and comparing with standard specimens’ endurance life. |
