A numerical process based on crystal plasticity finite element (CPFE) was implemented to
predict creep-fatigue crack initiation life. CPFE-based model can describe the macroscopic …

A series of strain-controlled creep-fatigue tests with various dwell times and strain ratios are
carried out on a nickel-based superalloy at 650° C. Aiming at the mechanical understanding …

To achieve a high-reliability design of high-temperature structures with a feasible balance
between accuracy and efficiency, the physics-based probabilistic assessment for creep …

Complex curvature and/or high-stiffened components are often in the elastic-plastic
deformation range during the loading stage of creep age forming (CAF) process. Effects of …

Providing a comprehensive assessment of the creep-fatigue life of critical structures in
nuclear power facilities is important for structural integrity and performance requirements …

In contrast to conventional strain-controlled creep-fatigue interaction (CCFI) loadings, a
novel hybrid stress-and strain-controlled creep-fatigue interaction (HCFI) loadings were …

This paper develops a robust creep-fatigue interaction (CFI) life prediction model which is
superior to the existing methods. Specifically, the newly proposed creep damage …

This paper presents creep-fatigue life evaluation of a nickel-based Alloy 740H, for
evaluating its performance as a material of advanced ultra-supercritical power plants. Strain …

Damages caused by the effects of cyclic loading (fatigue) and high temperature (creep and
oxidation) have been considered critical and need to be appropriately evaluated. A series of …

Interfacial creep failure was strongly affected by the solidified grain boundary (SGB) for
steel/nickel dissimilar metal welded joints, especially at higher temperatures and lower …
