.... The directionality of the features was found to be suggestive of shear overload. It was observed that fracture preferentially followed the nonmetallic inclusions. The fracture was revealed to be parallel to the direction of the manganese sulfide stringer inclusions. The presence of significant banding of the ferrite...

... property, K Ic . The underlying explanation for this observation follows from the preceding paragraph. Plane-strain conditions increase the hydrostatic stress and inhibit yielding. Under purely hydrostatic loading, no shear stresses exist, as is easily shown by examination of the three Mohr’s circles...
