Abstract


The method of cyclic creep-damage problem’s solution for aviation structural elements is presented. Finite element method and developed constitutive equations are used for the analysis of non-linear behavior at periodic modes of loading. The materials with and without creep recovery are considered. The results of numerical estimations of long term strength of gas turbine engine bodies are discussed.
