Preserved Fulltext
The influence of overload-induced crack deflections and bifurcations on the propagation behavior of mode I fatigue cracks is studied using specialized finite element (FE) software. The FE program is validated through comparisons between FE-calculated and analytical stress intensity factors (SIF) for a crack with a small kink at its tip. The SIF of bifurcated cracks are then obtained using the software. It is observed that such deviations of the crack path can cause significant growth retardation and even crack arrest.
