摘要：

Problems connected with analytical evaluation, based on the theory of adaptability, of the thermocyclic strength of gas turbine engine disks with concentrators, operating within a wide range of temperarures, are discussed. Methods of calculation of irreversible deformations, service life, and crack propagation velocity in the stress concentration region are considered. An algorithm of calculation of deformation in a disk, using the incremental theory of plasticity and a modified theory of creep, is described.
