A life prediction mod el for TBC was established for presenting the coupling effect of oxidation damage and thermal fatigue damage. 基于研究结果，建立了可以体现氧化损伤与热疲劳损伤耦合效应的寿命预测模型。
A viscoplastic constitutive model was introduced for the ceramic coat.Moreover, the thermal fatigue behavior of the coating layer was studied numerically. 针对陶瓷层材料引入粘塑性本构模型，对涂层的热疲劳进行数值模拟研究。
