Full-field displacement data, acquired by image correlation, have been used to determine the stress intensity factors for a fatigue crack emanating from a hole. In addition, seven different mixed mode (I + II) loads were applied to the AI7010 specimen. The elastic model employed for describing the displacement field around the crack was based on Muskhelishvili's complex variable formulation. Utilization was made of the multiple-points over-deterministic method for calculating the stress intensity factors. Good correlation was found between the experimentally determined and the nominal values of the stress intensity factors.
