Various criteria of multiaxial fatigue fracture are studied for low-cycle fatigue (LCF); their generalizations are proposed for a very-high-cycle fatigue (VHCF) regime. 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 disk operation are obtained for alternative mechanisms of LCF and VHCF using the calculated stress state and the models of multiaxial fatigue fracture. The results are compared with the data observed during operations.
