Influence of Partial Slip Conditions on Rolling Contact Fatigue of1070 Steel

摘要：

Partial slip rolling contact was analyzed in this paper by the finite element method with theapplication of a robust cyclic plasticity model.The repeated rolling contact process was carried out bytranslating the normal pressure and the tangential traction across the contact surface step by step.Thenormal pressure and the tangential traction were applied to the nodes through the time-dependantamplitude functions as the concentrated nodal forces.With the detailed stress-strain responses outputfrom the FE analysis,a general multiaxial fatigue criterion was used to predict fatigue initiation lifeand initiation position.The influences of partial slip conditions on the residual stresses,residual shearstrain and the initiation lives are obtained.
