热弹性材料的设计在功能梯度材料（FGMs），这减少了材料中诱导的热应力的直接灵敏度和优化方法与增量热弹性/热传导有限元分析的装置，是广义的，通过允许全空间分布的相的体积分数和非线性依赖的材料参数的体积分数。文中给出了内边界受非对称加热的空心圆柱体材料设计理论的数值例子。
Thermoelastic material design in functionally gradient materials (FGMs), which reduces the thermal stresses induced in the materials by means of the direct sensitivity and optimization methods associated with the incremental thermoelastic/heat conduction finite element analysis, is generalized by allowing full spatial distribution in the volume fraction of the phases and non-linear dependence of the material parameters on the volume fraction. Numerical illustration of the theory is given for material design in a hollow circular cylinder subjected to asymmetric heating on the inner boundary.
