FE‐Simulation based analysis of residual stresses and strain localizations in ECAP processing

FE‐Simulation based analysis of residual stresses and strain localizations in ECAP processing Equal Channel Angular Pressing (ECAP) is a method to introduce severe plastic deformation into a metal billet without changing it's profile. In special cases the strain localizes and so‐called shear and matrix bands are induced. These localizations are simulated and analyzed with respect to the residual stresses by using the finite element method. We found that in contrast to the components of the stress tensor, only a small difference in the von‐Mises stress between shear and matrix bands occurs. (© 2017 Wiley‐VCH Verlag GmbH & Co.

Abstract

Equal Channel Angular Pressing (ECAP) is a method to introduce severe plastic deformation into a metal billet without changing it's profile. In special cases the strain localizes and so‐called shear and matrix bands are induced. These localizations are simulated and analyzed with respect to the residual stresses by using the finite element method. We found that in contrast to the components of the stress tensor, only a small difference in the von‐Mises stress between shear and matrix bands occurs. (© 2017 Wiley‐VCH Verlag GmbH & Co.
