AB Most mechanical components experience multi-axial cyclic loading conditions during service.Experimental analysis of fatigue cracks under such conditions is not easy and most works tend to focus moreon the simpler but less realistic case of uni-axial loading. Consequently, there are many uncertainties related tothe load sequence effect that are now well known and are not normally incorporated into the growth models.The current work presents a new methodology for evaluating overload effect in biaxial fatigue cracks. Themethodology includes evaluation of mixed-mode (KI and KII) stress intensity factor and the Crack OpeningDisplacement for samples with and without overload cycle under biaxial loading. The methodology is testedunder a range of crack lengths. All crack-tip information is obtained with a hybrid methodology that combinesexperimental full-field digital image correlation data and Williams' elastic model describing the crack-tip field.
