Abstract
In the paper numerical analysis of the upsetting is presented with focus on the possibilities of the quality improvement by equalization of strain distribution with simultaneous reduction of the forging load. This goal is achieved by the use of multi-stroke progressive upsetting, which depends on sequential deformation of small portions of the total volume at reduced load. As the results show, this approach also allows reduction of nonuniformity of strain in the forged flange. Calculated fields of effective strain distribution and plots of its profile on cross-sections confirm the reasonability of technological modifications.
