Notes:
The residual stress accumulation of thermal barrier coatings (TBC) during thermal cycling hasbeen simulated by thermal elastic-plastic finite element method. Stability process of thermal barriercoatings during thermal cycling is studied by Melan's static shakedown theorem considering thermalgradients and thermal expansion misfit. The influences of the interfacial morphology of top coat / bondcoat (TC/BC) on residual stress and stability process are analyzed. Thus, the residual stress and stabilityprocess are affected remarkably by interfacial topography between TC and BC. Accidented interfacecause the sudden change of the interfacial residual stress which is harmful to interface bonding intensityand stabilization. It is useful information for studying of the life and final spallation of TBC system
