“…The numerical method such as finite element method is one of the most powerful tools of computer-aided engineering (CAE) to solve and simulate various problems in design and manufacturing, especially in the extrusion processes. Recently, some commercial CAE softwares are now available for analysis and being utilized for process verification and modification as well as for design improvement [1][2][3][4].…”

In this present paper, the combined-radial extrusion process at room temperature is considered. Computer-aided simulations by the rigid-plastic finite element program such as QForm 2D in two different schemes of combinedradial extrusion process, viz, single-ended and double-ended have been used. The die schemes, die geometry parameters, axisymmetric billet dimensions and power mode parameters to investigate forming characteristics such as deformation patterns (gridlines distortion), distributions of effective strain and stress and comparisons of loadstroke curve in these processes by using various relationships have been applied. Based on the simulation results, it isconcluded that the maximum forming load will be occur in single-ended process and the best strain-stress distributions will be appear in double-ended process.

“…The lateral extrusion is an important branch of the extrusion process to create non-axisymmetric parts. A billet is placed in a container and pressed by one or two opposite simple punches causing the radial material flow through a fixed die cavity [1][2][3][4][5][6][7][8][9][10].…”

In this paper, the cold lateral extrusion process of branch form is considered. A numerical simulation method such as the rigid-plastic finite element method (FEM) in two different schemes of lateral extrusion process, viz, single-ended and doubleended has been used. The die geometry parameters, billet dimensions and power mode parameters were used for investigating the material flow, stress-strain state and variation of punch load. Based on FE simulation using three-dimensional DEFORM software, forming characteristics such as deformation patterns (gridlines distortion), distributions of effective strain and stress, the variation of punch load with punch stroke and comparisons of load-stroke curve in single-ended and double-ended lateral extrusion processes by using various relationships have been investigated.

“…In 1996, Nishimura et al (1996) combined image-processing technology with injection upsetting and with reference to the morphologies associated with the adhesion between the die and the contact face of the material, analyzed the galling of the products due to bad lubrication. In 2001, Ko et al (2001) adopted rigid-plastic finite elements to perform simulation and analysis. They simulated three punch motions and studied the effect of the relevant parameters of the die on the shape of the flange during flange extrusion.…”
