梯度功能材料稳态温度场下的热应力分析

Study on thermal strain field of functional gradient material in steady temperature

采用一种新的显微数字散斑相关方法 ,对微薄层梯度材料在恒温热载荷情况下的应变场进行了实验研究 ,并与双材料恒温下的应变场进行了比较与分析。从而为优化设计和制备梯度功能材料提供了一种可行的实验方法和有意义的结果。

A new digital micro speckle correlation method was used to experimentally study the strain field of functional gradient material (FGM) in constant thermal load, and the results were compared with the strain filed for bi material in constant temperature field. This paper has offered a kind of feasible experiment method and meaningful results to optimum design and manufacturing of functional gradient material.
