The three dimensional flow in the plastic working process subjected to finite strain was studied with the aid of vector geometry. Relations between stream lines, velocity distributions, and principal directions of stresses were obtained by measuring deformations of grid lines on the cross sectional plane. The previous theories for finite strain in rotationally symmetric body, analyzed by Siebel and Huhne, require some corrections, especially for the additional shear increment, d(tanδ). Piercing process was used to obtain steady plastic flow of lead and aluminium, and it was found that there was little difference in flow between the hot working and cold working processes at room temperature.
