Abstract
In this paper, stress analysis of holed plates was implemented in order to estimate the fatigue life due to the combined effect of cold expansion and bolt tightening (clamping force). The fatigue life was divided into two phases of crack initiation life and fatigue crack growth life. The fatigue crack initiation and fatigue crack growth life estimations have been investigated numerically and the total estimated fatigue lives have been compared...
