Abstract: 

An attempt was made to investigate the thermal and residual stress distribution in a novel three layer (La2Zr2O7/ 8YSZ/ NiCrAlY) during a real-like heating regime. The technique of reduction of solving time like mass scaling leads to a considerable reduction in running time while satisfying and not violating accuracy and converging criteria and constrains. Simulation results indicated that, most of damaging and harmful distortion and residual stress concentrate on ceramic top coats and this lead less harm and life time reduction in substrate.
