Figure 6
The measured average residual stress and deconvoluted residual stress distribution in the TBC as a function of depth and stress calculated by our analytical model. The measured average stress is compressive and shows a nonlinear trend, increasing from the surface to the interface. The deconvoluted residual stress shows a similar trend to the average stress and the deconvoluted value is larger than the average value. The analytical model shows a linear trend with little difference from the surface to the interface. The deconvoluted value is consistent with the model at the interface but differs at the surface. |
