Abstract
A bushing () has two bushing parts (), each of which includes a tubular section () and a radial flange section () Tubular section () is inserted into an opening () in a work member (), from one side of the work member (). Tubular section () is inserted into tubular section () from the opposite side () of the work member (). A mandrel (M) is moved through the interior of the tubular portion of the bushing to radially and circumferentially expand the tubular portion of the bushing and move the flange sections against the opposite sidewalls of the work member (). The tubular portions () of the bushing () is radially and circumferentially expanded an amount sufficient to introduce fatigue life enhancing compressive residual stresses in the work member () immediately around the opening () in the work member ().
