  Article:   AN EXPERIMENTAL AND FINITE ELEMENT ANALYSIS OF MATERIAL FLOW DURING FORWARD EXTRUSION OF LEAD ALLOY.

Authors:  MARIANA POP.
 
       
         
  Abstract:  An experimental and finite element analysis (FEA) of forward extrusion of lead alloy were developed. In order to determine the deformation flow patterns, square grids were scribed on the meridional plane of one of the two matching halves of the splitted-lead specimens. A finite element analysis (FEA) of the cold forward extrusion process was undertaken in parallel with the experimental programme. Data obtained from the FE model included extrusion force, effective stress and strain and material deformation flow. The data obtained by numerical simulation confirm theoretical and experimental results.

Keywords: forward extrusion, die angle, ram speed, metal flow, finite element method
