Paper Abstract

In this paper, the holographic interferometry was used to real-time monitor extension procedure of crack in 30CrMnSiNi2A super-high strength steel, placed in corrosion environment. The experiment indicate that, this method can clearly display the change of interference fringes of strain at crack-tip, determine KISCC and fracture starting time of stress corrosion. Compared with other methods, it has obvious advantages.
