In Figure A3 the top left subfigure should be replaced as it is a duplicate of the center top subfigure. In the below figure, the top left subfigure of Figure A3 is replaced.
We would also like to make an adjustment to the text in section 3.4 Crack Path to better match the new image. In the first paragraph under section 3.4 Crack Path, the text should read:
The difference in crack path between the undeformed material PD0 and PD1 is small. Both show an inclined crack growth, but the crack propagates at a slightly shallower angle for PD1. However, as the degree of predeformation increases to PD3, a marked difference is observed. The crack now propagates closer to the direction of the microstructure alignment resulting from the predeformation, leading to a transverse fracture. For both duplicate PD3 test bars and one of the PD1 test bars, the final fatigue crack length prior to fracture is much shorter compared to the other cases. This indicates that at certain combinations of predeformation, crack geometry, and loading, the effective critical stress intensity is reached at shorter crack lengths.
