Abstrait:

With SSD algorithm and calculus process in detail computing, the basic calculation principles and the solution process from digital image to displacement of digital speckle correlation technology were described. Then the digital speckle correlation technology were used to the tensile test of CFRP plate embedded reinforcement beams, obtained the displacement cloud image and destruction rules of the specimens. The results show that the calculation results analyzed by the digital image correlation technology are in good agreement with the experimental phenomena. And the technology has the characteristic of full field measurement, simple operation, strong adaptability and high precision, so it has the widespread application prospect, especially suitable for application in the mechanical properties of materials under complex conditions, a large section of the destruction process monitoring and other fields.
