Abstract High sensitivity moiré interferometry was used to obtain whole-field orthogonal components of displacement in the vicinity of cracks in centre-cracked plates of aluminium 6082. The plates had been prepared in such a way as to enable the application of load at angles of 75° and 60° to the planes of the fatigue pre-cracks. The form of the moiré fringe data enables convenient separation of the components of stress intensity factor K I and K II. The results are compared with analytical predictions. The method is, in principle, suitable for use with specimens of arbitrary geometry and loading.
