State of Stress in Cylindrical Parts during Transverse Straightening

  • 1 Accesses

Abstract

Straightening by transverse bending followed by hardening by surface plastic deformation based on transverse spinning of cylindrical parts by flat plates is suggested to restore the shape of distorted low-rigidity cylindrical parts, such as shafts and axles. The Ansys Workbench software package is used to estimate the state of stress in a cylindrical part during transverse straightening. The distributions of the working and residual stresses over the cross section of a cylinder are obtained as a function of the relative reduction.
