Abstract
- An analytical model is first proposed for the determination of a friction-corrected flow stress in channel-die compression. A variational approach is then used for estimating the strain and strain-rate heterogeneities as well as the shape changes during deformation for two specimen geometries. The results are compared with finite element calculations. Results obtained from the two methods are in good agreement, except for the outer profiles of the deformed specimens. Finally, the various components of the powers involved in the deformation process are compared.
