In this paper, a numerical technique for analyzing one-dimensional steady-state and transient temperature distributions in a plate of functionally graded ceramic-metal-based materials(FGMs), in relation to both the temperature-dependent thermal properties and continuous/gradual variation of the thermal properties of the FGM, is presented. The FGM plate is assumed to initially have a steady-state temperature gradient, being exposed to high temperature on the ceramic surface and to low temperature on the metallic surface, similar to its in-service state. The FGM plate is then rapidly cooled from the ceramic surface side by cold medium. The steady-state and transient temperature distributions in the FGM plate are analyzed numerically for a model alumina-nickel FGM system. The proposed analytical technique for determining the temperature distribution is relatively simple and widely applicable compared with methods recently proposed by other researchers.
