Error Analysis of the Bending Tube Residual Stress Measurement System Based on Digital Speckle Correlation Method
In view of the bending tube residual stress measurement system based on digital speckle correlation method (DSCM), the main error elements are analyzed comprehensively. According to the theory of the error elements, the methods to reduce the errors are proposed. At the end, the error elements and the methods which reduce the errors are verified through an experiment. It is a useful reference to the similar measure system based on the digital speckle correlation method.
