Abstract: In this paper, the composite cylinder system is made of three layers: metal, functionally gradient material (FGM) and ceramics is studied. The formulas of the steadystate temperature distribution and the associate thermal stress distribution in the cylinder are obtained. For ZrO2/Ti6Al4V system, the distribution of steadystate temperature and thermal stress are calculated and discussed.

Key words: functionally gradient material, thermal stress, cylinder
