Abstract
Non-uniform, cold deformation of an elastic, strain-hardening cylinder in axial compression between two rigid and two elastic dies with comp lete sticking to the die-workpiece interface was studied using the fin ite element method. It is shown how the die elasticity influences the prediction of loads, the distribution of normal stresses, the appearan ce and growth of the plastic region. The results are verified experime ntally by microhardness tests performed on the upset specimens.
