摘要：

A general method for the analysis of the thermal stresses produced during cooling of plasma-sprayed thermal barrier coatings is presented. It relies on a model for the reproduction of the microstructural data presented in the previous (companion) paper. Homogenization theories are used, in conjunction with symbolic analysis, in order to obtain a piecewise homogeneous effective representation of the coating, starting from these data. The temperature portrait and the thermoelastic fields are numerically obtained respectively by finite difference and finite element methods.
