Abstract:

The criteria for stress corrosion crack branching in high-strength steels are shown to be 1 a constant crack velocity and 2 attainment of a critical stress intensity K sub Ib. For the steels investigated, values of K sub IbK sub Iscc range from 2 to 4. This indicates that when K sub IsccK sub Ic exceeds 0.5, rapid brittle fracture will occur before K sub Ib can be reached.
