%D 2009 %I COMSOL %T Finite element analysis of thermal fatigue in thermal barrier coatings (TBC) %B COMSOL conference 2009 : user presentation and proceedings CD : Boston, Milan, Bangalore %C Milan, Italy %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 %L eprints3821 %A Claudia Borri %A Alessandro Lavacchi %A Alessio Fossati %A Ilaria Perissi %A Ugo Bardi
