Cracks in mechanical structures lead to serious destruction accidents. High precision detection of cracks and evaluation of mechanical parameter of crack are important issues in order to prevent destruction accidents. In this study, we developed a crack detection method by digital correlation method which can evaluate the strain distribution from the surface image. Using this method, the stress intensity factors for mode I and mode II can be evaluated from sample surface. It also can be used to evaluate the inclination angle of the cracks.
