功能梯度材料是一种集高强度与高耐热性于一体的新型复合材料。本文重点对组分分布模型和物性参数模型进行了分析比较，讨论了组分分布系数、物性参数、空隙率等因素对残余热应力的影响，对FGM热应力研究领域的发展趋势做了一些展望。%Functionally graded material (FGM) is a new composite material with high-strength and high heat resistance. This article compares the component distribution model and physical parameter model and discusses the influence of component distribution coefficient, physical, voidage and other factors on the thermal residual stress. The development trends of FGM thermal stress research is prospected.
