Abstract
• Fatigue crack growth rate (FCGR) for high-strength steel was studied experimentally. • FCGR under various overload ratio, overload interval, and load sequence was obtained. • FCGR under ‘Storm model’ and superimposed loadings was obtained. • Plastic zone around crack tip was obtained by digital image correlation (DIC) method. • FCGR was predicted by a modified Wheeler model combined with DIC method. In this paper, aimed at high strength steel...
