Résumé

Thermal barrier coating life modelling is a major challenge for industrial applications. This study aims to highlight critical damage mechanisms involved in TBC failure for both isothermal and cyclic oxidation conditions. Experimental database is analysed in relation to elastic buckling of the ceramic top coat obtained by mechanical compressive tests. Ageing is modelled thanks to an original damage approach dealing with the evolution of interfacial properties and loading history. This methodology is successfully applied as a post-processor to a 3D blade simulation for typical thermo-mechanical fatigue in-service loading.
