Abstract

Accurate life assessment and reasonable description of cyclic deformation of the material and related components considering the creep-fatigue damage of the material is an important issue for long period safety of the aero-engine under cyclic thermal-mechanical loading conditions. Based on the finite element code ABAQUS, a cyclic elasto-plastic constitutive model combining the Chaboche nonlinear kinematic hardening rule and Voce's isotropic hardening rule is firstly employed. Then with the help of an additional strain-hardening creep constitutive model, the creep-fatigue cyclic deformation behavior of the GH4169 alloy including the peak stress relaxation period is simulated accurately. Based on the simulated cyclic stress-strain state with the finite element method, accurate life prediction of the GH4169 alloy are accurately realized by numerically implementing Wang's modified creep-fatigue damage model on the basis of the cycle-by-cycle concept. Our result will provide theoretical basis and technical support for further realization of accurate prediction of the creep-fatigue life of key components of the aero-engine.
