Abstract: Numerical simulation of extrusion process of aluminium tube is dealt with using the finite element polycrystal model. The non-uniformity in plastic anisotropies of aluminium extruded tubes through the wall thickness is investigated.

Key words: FEM  Polycrystal model  Plastic  Anisotropy  Aluminium tube  Extrusion
