Abstract—A finite element model is constructed to analyze the steady heat conduction and thermal stress in a ceramic/FGM/metal composite EFBF plate under convective heat transfer boundary. From numerical calculation, when T0=Ta =300K and Tb=1 800K, the steady heat conduction and thermal stress distributions in the plate were obtained. The numerical results show that the temperature distribution in the composite plate is more reasonable with the increase of the FGM layer thickness, and compared with h2=2mm the maximum tensile stress of h2=6mm reduces by 36.3%. With the increase of M, the temperature on the surface of ceramics reduces by 6.2%, the compressive stress on the metal surface reduces by 28.3%, and the compressive stress on the surface of ceramics increases by 70.2%. With the increase of porosity, there is an abrupt change for temperature at the y 0.48, its value is 875 K, and the change of stress at the interface of the three-layered plate increases, and the tensile stress on the surface of ceramics reaches the maximum. Compared with 1 a b  when 10 a b, the temperature on the surface of metal reduces by 23.9% and the temperature on the surface of ceramics increases by 44.4%, and the stress on the metal surface increases by 148% and the stress on the ceramic surface increases by 165%. Compared with the nongraded two-layered composite plate, the temperature and the thermal stress of the ceramic/FGM/metal composite plate are very gentle and smooth. The results provide the foundations of theoretical calculation for the design and application of the composite plate.
