Abstract

The interference behavior of two surface fatigue cracks on A7050-T7451 aluminum alloy was investigated by replication technique and micro computed tomography (μCT) with synchrotron radiation of SPring-8. From the results, fatigue crack propagation behavior inside the specimen was obtained. And furthermore, values of stress intensity factor of the crack tip inside the specimen were estimated by using the crack propagation rate which were obtained from, reconstruction images of fatigue crack for Paris's law.
