The behavior of short and very short fatigue cracks, emanating from so called “smooth” specimens with stress concentrations has been an intriguing research topic for a long time. It is well known that micro-cracks are embedded in the surface of any smooth specimen and are created during the manufacturing process. A few of these micro-cracks will eventually propagate due to fatigue loads and will become major cracks. Due to a combination of high local stresses and stress concentrations, the short cracks are the first to become the major cracks and eventually cause failure.
