Abstract

The 3D finite element analysis of aluminum extrusion is challenging due to, amongst others, the advanced geometries, the large number of unknowns and the complex boundary conditions involved. In the present paper a mesh generator is presented that is capable of generating meshes for complex geometries while reducing the resulting number of unknowns with directional refinement. With the meshes 3D thermo-mechanical computations are performed to determine the influence of the die geometry, in particular the bearing length, on the velocity with which the aluminum exits the die. Comparison of the computations with experiments reveals that, even though the trends are correct, the influence of the bearing on the exit velocity is overestimated.
