Abstract

The purpose of this research is to use the finite element method to successfully simulate the extrusion of powder/metal composite clad rods. This study is divided into two subjects. One is to obtain the material parameters of Drucker-Prager/Cap yield criterion for the powder by means of experimental methods. The other is to simulate the extrusion processes by using the derived material properties in the analysis. The material parameters of yield criterion were obtained from direct shear tests and constrained compression tests. The finite element simulation cooperated with this yield criterion displayed a good agreement with extrusion experiments. From the results of the analyses, it was concluded that the extrusion ratio was one major working parameter for the flow of the powder during the extrusion processes.
