Spring Back and Secondary Yielding Analyses Using A Physically Based Constitutive Model

  • X. Peng

Abstract

A material user subroutine, UMAT, was programmed for embedding in the commercial software, ABAQUS, together with a new constitutive model for large elastoplastic deformation and the corresponding numerical algorithm. The spring back and secondary yielding of cylindrical billets in elastic tools during upsetting and closed-die upsetting were analysed. The comparison between the computed and experimental results shows satisfactory agreement.
