A computational model is proposed for the determination of the service life of structural elements with concentrators under the conditions fatigue and high-temperature creep. The model is based on the energy approach and the representation of the service life of a structural element as the sum of the periods of initiation and subcritical growth of creep-fatigue cracks.
