13th International Conference on Fracture June 16–21, 2013, Beijing, China -9- implying that there was no influence of hydrogen up to the yield stress of the steel; 3. There were surface cracks in the necked region on the specimens tested under hydrogen charging, implying that the influence of hydrogen was associated with the final ductile fracture process after the onset of necking.
