Abstract: Different criteria of the multiaxial fatigue fracture are studied for low-cycle fatigue (LCF) and their generalizations are proposed for very-high-cycle fatigue regime (VHCF). The procedure of the stress state calculation is described for the compressor disk of the gas turbine engine (GTE) in the flight cycle of loading and for the low-amplitude vibrations of the blades. The durability estimations of the disc operation are obtained for alternative mechanisms of fatigue LCF and VHCF using the calculated stress state and the models of multiaxial fatigue fracture. The results are compared with observed data during operation.

Keywords: low-cycle fatigue, very-high-cycle fatigue, durability estimation, stress concentration, centrifugal loading, high-frequency vibrations.
