| Abstract: | Simulation of multiple plastic bending deformations processes with loadings vice versa needs suitable parameters. For high‐strength spring steel there are not enough investigations available. Investigation and comparison of appropriate parameters for 54SiCr6 will be shown. On the one hand the results of tensile/pressure trials at 54SiCr6 shows that Bauschinger‐Effect is existing. Dependence of tangent modulus and plastic reverse deformation to degree of plastic deformation are obvious. Tangent modulus is decreasing according to increasing plastic deformation – plastic reverse deformation increases according to increasing plastic deformation. Investigated parameters probably depend to degree of plastic deformation and do presumable not accord to deformation history. |
