Abstract

Stress corrosion damage has a great proportion in modern machine engineering. The danger resulted from it is because corrosion crack is fine and not easy to be found by eyes. Therefore, it's important to study stress corrosion fracture in the field of engineering fracture mechanics. In this paper, the real-time method and double-exposure method in holographic interferometry are used to monitor and measure crack extension procedure in high-strength steel placed in corrosion environment, and record holographic interferogram. The test results indicate that this method can display clearly change procedure of strain interference fringes at crack-tip, determine stress corrosion fracture starting point of stress corrosion and K_ISCC. Compared with other methods, it has obvious advantages.
