【Abstract】 The steady temperature fields in the plate made of a functionally gradient material that consists of ZrO2 and Ti6Al4V with convective heat transfer boundary are analyzed by finite element method(FEM). The accuracy of this method is examined. The steady temperature field distributions under the convective heat transfer boundary are obtained.From the numerical results it can be seen that the temperature distributions are substantially changed with the change of the temperature of the surrounding, the parameter M, the porosity P and the convective heat transfer coefficients. The results may provide the foundations of calculation for material design and further thermal stress analysis.更多还原
