The goal of this work is to numerically show by using finite element method the influence of key factors on the mechanical response of a workpiece in equal channel angular extrusion (ECAE) process. Various geometrical parameters (channel angle, outer corner angle and inner radius) and material properties were considered in the numerical calculations with a view to the use of the process to polymers.
