TGO growth is based on the diffusion-reaction equations. TGO profiles and thickness obtained by FEM are in good agreement with the experimental observations reported in the literature. Thereafter, a simple cylinder theory model based on large deformation theory is developed to explain the stress fields simulated through FEM. In the model, TGO growth is described by growth deformation gradient, and then the total deformation gradient is decomposed into elastic deformation gradient and growth deformation gradient. The results obtained by theory model validate the finite element method for TGO growth stress simulation. So it is an effective approach to calculate stress distributions and TGO thickness simultaneously which are important for predicting the failure positions and lifetime of TBCs.
