The aim of this paper was to investigate the creep deformation of coating-based system under in-plane bending moment. An analytical model was proposed to predict the creep strain and stress within the coating-based system through extending the classic beam theory. Once the material properties and thicknesses of the coating and substrate were identified, the implementation of the model was fairly straightforward. A basic understanding of the time-dependent behavior of the coating-based systems was achieved by using this model, which can be used to guide their design and fabrication. Specific results were calculated for the time-dependent curvatures of the NiCrAlY coating/IN718 substrate systems, and the stresses as well as strains in them. The effects of the exposure time, coating thickness, and creep-law parameter of the coating on the stress and curvature of the coating-based systems were discussed.
