| Abstract: | In this paper,by studying a laminated cylinder made of three layers of metal-func-tionally gradient materialceramic, the formulas of the temperature and the steady thermalstresses in the cylinder are obtained. Based on the strength theory, the design of thermalstress relaxation was carred out under different ZrO2/Ti-6Al-4V FGM compositions. Thecalculated results show that the functionally gradient material has better thermal stresses re-laxation and the model is more practical. |
