Experiment Study of Thermal Strain Field of Functionally Gradient Material

本文采用显微数字散斑相关方法 ,对梯度材料在稳态梯度温度场分布状态下应变场进行了实验与理论计算的研究 ,并对结果进行了比较与分析 .从而为研究、设计、制备梯度功能材料提供了实验方法 ,并可为梯度材料理论研究的发展提供依据 .

In this paper, digital micro speckle correlation method is used to calculate strain filed of functionally gradient material(FGM) in steady stable temperature filed, and the results are compared with the strain filed that the theoretical result of strain and stress in same thermal field. This paper has offered a kind of feasible experiment method and meaningful results to design and prepare functionally gradient material, and it is the basic of theory research of FGM material.
