In the following paper results of the investigation of the “Bauschinger effect” are presented. It was done by model which was made in ABAQUS and observed from deep rolling simulation results of residual stresses. Later, comparison of the results are presented by variation of forces and overlapping factor. Deep rolling (DR) is a mechanical surface treatment widely used due to its ability to increase the fatique life of the treated components. The finite element analysis (FEA) is a convenient tool which can be used to model the DR process and facilitate its implementation in to new components. A central aspect in the FE modeling is the material definition and particularly presence of the mechanical phenomenon called “Bauschinger effect”. The material used for the simulation was a steel alloy 42CrMoS4 with mass density of 7720 kg/m3, Young Modulus of 210 MPa, Poisson’s ratio of 0.28 and plastic hardening type was defined as a kinematic.
