STRESS CORROSION CRACK BRANCHING IN HIGH-STRENGTH STEELS

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 Ib/K sub Iscc range from 2 to 4. This indicates that when K sub Iscc/K sub Ic exceeds 0.5, rapid brittle fracture will occur before K sub Ib can be reached.
