Abstract

This paper analyzes the propagation behavior of fatigue cracks arising from contact loading. Stress intensity factors are computed for a surface breaking crack in the presence of a near-surface inclusion, and under the influence of interacting asperities at the surface. Crack arrest is examined, the role of inclusions demonstrated, and a single-crack load-life calculation is performed, yielding results consistent with experimental observation. Finally, stress intensity factors are computed for a subsurface crack growing from an inclusion toward the surface.
