SHAKEDOWN ANALYSIS OF MORPHOLOGICAL DEFECT IN THERMAL BARRIER COATING

摘要：

Morphological defect and cumulation of residual stress represent a source of failure in some thermal barrier systems during high temperature operation. A simple analytical model of three concentric circles is adopted to represent top coat, oxide coat and bond coat of thermal barrier coating. The model denotes interface morphological defect of thermal barrier coating. A self-equilibrated residual thermal stresses is given based on simple analytical model of three concentric circles, and then a shakedown analysis is established based on the model. The result is important to stabilities research of thermal barrier coating.
