摘要：
This paper deals with the development of a fatigue crack growth model for high temperature complex loading and application to turbine disc conditions. The proposed model is based on an extensive experimental study performed on Astroloy at 650-degrees-C, which comprises fatigue with or without hold times, special tests with holds at intermediate loads, fast-slow or slow-fast triangular waves, sequence tests, etc. The crack growth model is built up in the framework of classical linear elastic fracture mechanics. Its structure is quite simple and is supported by previously developed fatigue crack growth models and a companion study made at Ecole des Mines de Paris (EMP) for the oxidation processes on Astroloy.
