Abstract

The authors present the results of the experimental investigations on the cyclic creep of steel 10GN2MFA at a complex stress state taking into account the damage kinetics. Considerations concerning the evaluation of the creep strain accumulation process taking into account the damage are given with the help of an elastic-viscoplastic model. The interrelationship between the viscoplastic properties of the investigated steel and the damage kinetics under cyclic loading at different stress state types is found.
