Fatigue crack initiation life of a structure may be determined by local mechanical conditions such as local stress and/or strain, and by local material properties. The present work is intended to predict fatigue crack initiation life of a structure by means of local fatigue concept and fatigue behaviors of smooth specimens. 4 kinds of Al alloys were tested to investigate the cyclic hardening properties and failure lives by strain control fatigue tests. Load control fatigue tests were performed to observe crack initiation behaviors in notched specimens (K_t=2.3). The effect of cyclic hardening properties on local bahaviors in notch tip was also discussed.
