Surface crack initiation in pure titanium under various stress frequencies

Journal Article · · Engineering Fracture Mechanics
OSTI ID:85468

The effect of stress frequency on fatigue surface crack initiation in 99.5% pure titanium, which has remarkable strain rate dependence in the plastic region, was studied by experiment and FE analysis. Surface crack initiation tests were carried out under three different stress frequencies. In this analysis, 3D elastoviscoplastic FEM-code was used. A comparison between the surface crack initiation life and the behaviors of the stress concentration part by analysis was made. 5 refs.
