The aim of this study is to build a lifetime assessment model for thermal barrier coatings protecting aircraftturbine blades, by setting up and using adhesion tests. The model involves three steps: first, the mechanicalfields inside the layers are computed by a semi-analytical model of the multi-layered system behaviour, whichwas improved to fit the industrial demands. Given the thermo-mechanical history of the substrate (which canbe derived from FE computations), the model computes the interface strains between the metallic substrateand the ceramic protection under a stress field induced by oxidation. The model has been identified andvalidated with respect to rumpling measurements for different ageing temperatures of the system.During a se...
