Abstract

Real-time fine-grid-method was applied to fatigue crack initiation and subsequent 'small crack' growth processes at the area of notch-root. Special attention was focused on not only local-strain behavior at the notch-root until crack initiation but local crack-tip strain change of 'small crack' growing from notch-root. As a result, fatigue crack initiation cycle was controlled by local-strain damage accumulation. Growth rate of 'small crack' could be successfully evaluated by our proposed parameter of local crack-tip strain range, DELTA epsilon ** tau .
