%X A Finite element model of plasma sprayed  TBC’s was developed to estimate the stress  induced by thermal cycling experiments. A heat  transfer analysis was performed to evaluate the  temperature distribution on the specimen during the cooling under an impinging air jet; temperature measurements performed with an infrared pyrometer on the cooled samples show good agreement with the evaluated data. These results were then integrated in a structural  mechanic model as thermal load. The COMSOL Multiphysics® Thermal-Structural interaction model allowed to determine the dependence of the stress on the temperature fields
