N2 - The use of heterogeneous bond coats to increase the durability of plasma-sprayed thermal barrier coatings under spatially cyclic thermal loading was examined. The evolution of local stress and inelastic strain field in the vicinity of the rough top/bond coat interface during thermal cycling was analyzed. The higher-order theory for functionally graded materials was used in conducting the analysis. It was shown that the use of heterogeneous, two-phase bond coats increases the magnitude of the shear stress component.
