Numerical simulation of relation between interface topography and residual stress in thermal barrier coatings
Guo-Feng Yao, Hong-Mei Ma and Lin-wen Zhang

 
Abstract
    With respect to thermal barrier coating, the analysis of interface cohesion and residual stress is important to the life of TBC from mechanical view point. Up to now, there is not a model of describing
interface cohesion. In the paper, we give a simple model of computing residual stress and study the residual stress of TBC with ANSYS. The distribution of the residual stress in different interface topography and the relationship between the residual stress and the interface topography dimension are presented.
 
Key Words
    thermal barrier coatings; numerical simulation; residual stress; interface topography.
