| Abstract: | This paper utilizes the common finite element software QFORM to simulate extrusion process for porous materials., and analyzes the relation between mean stress and relative density, and studies the influence of initial relative density to speed of densification and extrusion force. These can provide theoretical reference to process design, die design and improvement of product's performance. |
