The study of residual stresses in cold drawn steel wire by means of X-ray diffraction and finite element simulation

摘要

Residual stresses caused by cold drawing of low carbon steel wires have been studied. A wire was drawn from 20 mm diameter until 18 mm in one pass An elastoplastic FEM simulation was performed using several constitutive models for the material. One of them takes the anisotropy due to the crystallographic texture into account. The predicted residual stresses were then compared with those obtained by X-ray diffraction measurements. A good agreement was found.
