Original abstract

Large plastic deformation of cold formed metal is followed by its hardening, which can be experimentally evaluated by measuring of hardness. New procedure of strain- hardness evaluation is suggested here, based on FE simulation of a forming process and direct reletion of computed strain and measured hardness. The procedure is ilustrated on the example of forward extrusion process and reference curves, obtained by classical and newly suggested procedure are compared.
