摘要：
Cracks can be formed at interfaces by dislocation of pile-ups. Unexpectedly large plastic strain was always associated with crack propagation. To confirm this observation, measurement of the plastic strain at the root of the notch of the augmented strain cracking test specimen of HY-130 steel was conducted on both electrolytically hydrogen-charged and hydrogen-free specimens.
