Abstract

Issues on increasing the fatigue resistance of shafts by applying the method of surface plastic deformation (SPD) are considered. The factors (the shaft dimensions and shapes, the stress concentration, surface strengthening) are analyzed, and regression equations for their quantitative estimation and application in design calculations are obtained.
