The present paper exposes the development of a specific Digital Image Correlation (DIC) method to ensure a fast calculation of fracture parameters such as stress intensity factors and crack length. This measurement is used to control a fatigue crack propagation using the load shedding method in order to ensure a limited plastic damaged crack. The experimental procedure has the main advantage to be fully automotive. The parameters’ identification is compared with a more sophisticated identification method and shows a good accuracy.
