Abstract: The aim of this work is to investigate the barreling of aluminium cylinders having two different aspect ratios in terms of barrel profiles and required loads. A modified upper bound solution including a dimensionless optimizing parameter for uniaxial upsetting has been developed and the loads calculated thereby have been compared with the results of several experiments conducted. Furthermore, the barrel profile is firstly assumed as a second-order polynomial for the upsetting process and an empirical correlation between the billet dimensions and the barrel profile has been established using experimental data. AA6082 is used as test material. The experiments are carried out on a 150 metric ton capacity hydraulic press. Besides, the bulging profile and effective strain distribution of the billets are obtained with a commercially FEM program called DEFORM 3D.
