摘要：
Elasto-plastic finite element analysis was carried out for analyzing the severe plastic deformation behavior of copper specimens during groove pressing. Deformation localization was studied in terms of strain variations along the longitudinal direction. Plastic strain is lower at the local interface between the shear and the flat regions, which receives very little shear during the pressing cycle. Strain localization is more intensified with the number of groove pressing cycles, although the average strain level increases. (C) 2008 Elsevier B.V. All rights reserved.
