Abstract : A flow line function is proposed to describe the material deformation in ECAE for a 120° die. This new analytical approach is incorporated into a viscoplastic self-consistent polycrystal code to simulate the texture evolution in Route A of copper and compared to experimental textures as well as to those corresponding to simple shear.
