Abstract
A novel detection method based on digital speckle correlation is proposed for the tensile test of sheet metal. Standardized covariance correlation formula is adapted according to the specimen’s tensile deformation. Also a new calibration method employing specimen as the calibrate object is presented combination with edge detection techniques. Purposing to improve the accuracy and rates of correlation search, the edge tracking measure results are adopted as the initial value of correlation search. And the feasibility of this set of method is proved by silica gel tensile tests.
