摘要：
Heavy-duty gas turbine blades, which contain film cooling holes, are subjected to a complicated dynamic mechanical loading. Special material tests have been developed to ensure the long-term operational reliability of the blading. This paper presents results of the testing and appropriate finite element (FE-) calculations, showing that a reliable fatigue life assessment can be achieved with the local approach concept.
