The effect of increasing loading angle or the mode III loading contribution on the size and shape of the plastic zone ahead of the crack tip were experimentally determined in Armco Iron. It was found that the shape of the experimentally measured plastic zone was in agreement with numerical prediction. However, the size of the measured plastic zones was significantly larger than the numerically predicted plastic zones for all the loading angles. The plastic zone was found to increase in the trajectory of a crack with increasing loading angle.
