Description
Summary:To solve the optimization problem of edge distance in titanium alloy sheet during a new aircraft development stage,a three dimensional FE model was built on ABAQUS platfom. The effect of edge distance on residual stress distribution was analysised with TC4 titanium alloy by interference-fit strengthening technique under cylic loading. The study indicates that a considerble reduction of fatigue life is found with a lower egde distance ratio( L/D),also,the location of fatigue damage is moving against the hole. Fatigue damage happens in the margin part with edge distance ratio( L/D) less than 2.
