Fracture Analysis of Thermal Barrier Coating Delamination under Thermal Shock

Thermal barrier coatings are widely used in section of turbine engines. The effect of a transient thermal load on a coating which is bonded to a square substrate is analyzed using FEM method. Coatings are assumed to contain embedded cracks and they are thermally loaded according toa transientlow temperature environment. Thermal barrier coatingmixed I/II mode fracture criterion was established, Our models take into account various locations of...
