| Abstract: | In this paper,the transient temperature fields and corresponding thermal stress distributions of the gas turbine stator blade made from silicon nitride ceramic materials are elaborately analyzed by the three dimensional finite element method. Numerical computation is assumed during the turbine ignition period when severe thermal shock in the heated parts occurs.The computational results obtained can provide fundamental information for destruction analysis and life prediction of the high-temperature ceramic turbine components. |
