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 steady-state temperature distribution and the associate thermal stress distribution in the cylinder are obtained.For ZrO₂/Ti6Al4V system,the distribution of steady_state temperature and thermal stress are calculated and discussed.
