Thermomechanically metallic components

Thermal-barrier coatings are used as thermal insulators to lower the temperature of the metallic components. Failure of TBCs is generally the result of thermomechanical processes. These processes are complex and depend on many variables associated with the coating and exposure environment. 

The way in which each individual SOFC component responds to stress varies widely depending on the physical conditions under which the deformation takes place and the mechanical properties of the materials. As the stiffness and strength of the material are closely interrelated, it is exceedingly important to describe the material behavior of the components to be modeled. The components usually employed in SOFC technology comprise the cell components that are usually investigated as a continuum layer, sealants, wire mesh, and the metallic components, that is, the interconnector plate and frame. This section outlines the mathematical formulation of the thermomechanically induced stress within each individual component.
