Abstract
One or more crack inhibitors can be installed to improve fatigue performance by producing stress states that prevent or inhibit crack initiation. Crack inhibitors can also prevent or retard crack growth. A mandrel can be used to radially expand the crack inhibitors to both induce compressive residual stresses and to form an interference fit between the crack inhibitor and a workpiece. The mandrel can be removed from the installed crack inhibitor, which is left in the workpiece to ensure proper stress states are maintained.
