A member has a wave inhibitor adapted to control the effects of a wave of longitudinally displaced material positioned ahead of an expansion mandrel used to expand the member. The wave inhibitor has a decreasing transverse cross-sectional area to diminish the effects attributable to the wave, such as workpiece distortions, material upset of the workpiece, lengthening of the member, and excessively high strains in the workpiece. The wave inhibitor can also induce radially compressive stresses in the workpiece and produce an interference fit.

A nut plate assembly includes a nut retainer and a bushing for expanding a tubular body of the retainer. The retainer assembly is used to cold work an opening of a workpiece in order to fix the nut retainer assembly relative to the workpiece. A nut can be snapped into the retainer. A method of installation includes passing a mandrel through the bushing to radially expand the bushing into a tubular body of the retainer. The tubular body is compressed between the workpiece and bushing as the bushing is displaced radially causing corresponding radial displacement of the tubular body. The expanded bushing applies pressure to the tubular body for a desired fit between the nut retainer and workpiece.
