Abstract

A general method for the analysis of the thermal stresses of plasma-sprayed thermal barrier coatings is presented. It employs a simulation technique for the reproduction of the microstructural data. Homogenization theories are used, in conjunction with symbolic analysis, in order to obtain a piece-wise homogeneous effective representation of the coating, starting from these data. The temperature portrait and the thermo-elastic fields are numerically obtained.
