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 method of speckle speckle correlation was used to study the strain field of a thin layer of gradient material under constant temperature and thermal load. The strain field under constant temperature was compared and analyzed. Thus providing a feasible experimental method and meaningful results for optimizing the design and preparation of gradient functional materials.
