      Mechanical test data for thermal barrier coatings, including modulus, static strength, and fatigue strength data, are reviewed in support of the development of durability models for heat engine applica-tions. The materials include 7 and 8 wt % yttria partially stabilized zirconia (PSZ) as well as a cermet ma-terial (PSZ +10 wt % NiCoCrAlY).Cited by: Stresses and Lifetime in Thermal Barrier Coatings -M.

    The model is calibrated against and verified for results from fatigue tests. By comparison of model predictions with results from test with different conditions, the model is shown to be capable of predicting results with good accuracy. KEYWORDS thermal barrier coating, thermomechanical fatigue, modeling, fracture mechanics, delamination.   Thin thermal barrier coatings (TBCs) for protecting aircraft turbine section airfoils are examined. The discussion focuses on those advances that led first to TBC use for component life extension and more re-cently as an integral part of airfoil design. Development has been driven by laboratory rig and furnace testing, corroborated by engine testing and engine field by:

    Thermal Barrier Coating Modeling TBC modeling is important for life prediction, understanding TBC behavior, and design of new coatings. Life prediction is the primary modeling issue that is needed to obtain the maximum benefit of TBCs apart from process modeling, which is .
