摘要：

This paper presents observations on fatigue initiation in friction stir welded AA2024-T3 Joints Based on these observations the influence of the weld on the location of initiation is discussed These locations of initiation are correlated to stress results from numerical analysis Furthermore fractography was performed to investigate the role of the microstructure in the weld on the location of initiation As a result It has been observed in which cases the residual stress determines the location of initiation and in which cases the microstructure (C) 2010 Elsevier Ltd All rights reserved
