Abstract
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.
