%X Photoelasticity is an effective method for structure internal stress distribution study, and is widely applied in engineering practice. Separation of principal stress is the key and difficult point in data analysis. In order to achieve that, an additional fuction is necessary. In this paper, Photoelasticity-Digital Speckle Correlation Hybrid Method is introduced to this problem. This method has combined photoelasticity method with digital speckle correlation method. On the basis of theory study, experimental system for Photoelasticity-Digital Speckle Correlation Hybrid Method were also designed. Corresponding three-point bending experiment was carried out to verify the effectiveness of this experimental system.This study may provide theoretical and experimental foundation for Dynamic Photoelasticity-Digital Speckle Correlation Hybrid Method.
