Notes:
With the knowledge of heterogeneous characteristics of thermal barrier coating materialsat mesoscopic level, a coupled thermo-mechanical-damage (TMD Model) model was introduced andused to numerically quantify the thermal stresses and crack development of in thermal barrier coatings(TBCs) composite subjected to decreased temperatures. The effect of different surface precrackmorphologies, such as precrack length and precrack density, on an interface crack subjected tothermal loading caused by a temperature change is presented. It provides us with a more sensiblephysical intuition and a more accurate mathematical for optimizing the design and the processing ofceramic coatings subjected to the coupled thermal-mechanical loading
