Analysis of forward–backward-radial extrusion process

This paper presents the analysis of forward–backward-radial extrusion process. Finite element method has been used to investigate the effect of geometrical parameters such as die corner radius and gap height as well as process condition such as friction on the process. ABAQUS software is used for finite element simulations. The finite element results are compared with experimental data in terms of forming load and material flow in different regions. Hardness distribution in longitudinal cross-section of the product is also used to verify strain distribution obtained from finite element analysis. The comparison between the theoretical and the experimental results show good agreement. The relation between hardness and strain value is compatible with previous work.
