Compressive residual stresses result from OPPT, provided the proof pressure is sufficiently high to cause tensile plastic yielding at localized regions such as fillets or other stress concentrations. Localized compressive residual stresses are unquestionably beneficial in mitigating service...

..., by producing residual compressive stresses on the surface, it is possible to reduce the crack growth during cyclic loading. As shown in Fig. 5.14 , the local residual compressive stress at the surface will cause the tensile stress on the rotating axle to decrease, because the cyclic stress produced...
