摘要：

A methodology, based on a combined numerical-experimental approach, was developed to evaluate friction coefficient at the die-workpiece surface in tube drawing. In the experimental stage the upsetting sliding method, performed under contact conditions, in terms of contact normal stress and equivalent plastic strain, similar to those encountered in the tube drawing process under investigation, was used. The values of friction coefficient calculated were dependent on tube geometry.
