分别以陶瓷／金属复合平板和圆筒为研究对象，导出了功能梯度材料组份连续变化下的温度及热应力分布，并将ＺｒＯ２／ＮｉＣｒＡｌ复合板热应力分布的解析解与有限元结果进行了比较，对复合圆筒进行了组份分布的热应力缓和特性设计。分析结果表明，用连续模型计算，可进一步减缓功能梯度材料层间的应力突变和残余应力，便于结构的优化设计。
Taking the ceramic / metal composite plate and the cylinder as the research objects, the temperature and thermal stress distributions of the functional gradient material components were deduced continuously. The analytical solutions and the finite element results of the thermal stress distribution of the ZrO2 / NiCrAl composite plate In comparison, the design of the thermal stress relaxation characteristics of the composite cylinder was carried out. The results show that the continuous model calculation can further reduce the stress gradient and residual stress between the functionally graded material layers and facilitate the structural optimization design.
